funding for this program was provided by the Force equals mass times acceleration mechanics the science of motion can be summarized in that one equation f equals Ma history of classical mechanics 1543 Copernicus Road city world Toyota Tacoma include even 50 years later it's still in Ruins and there was nothing to take its place some progress has been made and discovered falling bodies were understood and then in one breath taking book Isaac Newton invented physics as we know it today and restored order to the heavens and the Earth I'm trying to describe the basic Machinery of the world natural question is where did Isaac Newton speed explain the motion of almost everything on an above the surface of the year profoundly powerful equation equals mass times acceleration understand that equation it's possible to understand the Mechanical Universe at the same time I understand but considerable complexity what appears to be pure and simple closer look at people's inmate 3D TV deals to complications people's energy is a vector equation those Force acceleration are vectors in other words they have definite directions they must have the same direction the second complication arises in the symbol a for acceleration remember acceleration isn't the how fast something changes its position acceleration is how fast something gets faster acceleration heredity and Isaac Newton simple equation f equals ma about a derivative of a derivative for example when a body or Mass. so they're minutes equals how many acceleration and force in the same direction complicated beautiful in its simplicity that's the well-known equation in the case of a falling body what's new about acceleration for one thing and do another it's the same for all falling body what's more it's called G the force of gravity every falling body equals its mass times the acceleration power Direction but this equation also describes motion for other than gravity exerts the same force on a body no matter which direction that body travel what's an object in motion side from air resistance the only force acting on it but the drop from the tower shop from The Towering Mountain more games by The Towering mountain of a man measure are moving objects fall under the influence of gravity is power to see how it really works necessary to go back to the beginning this first of all embrace the idea of inertia hero every continues in its state of rest or Motion in a straight line unless it is compelled to change the font inertia ideas of Newton from Galileo it was an extraordinary modern images of something along these lines what's a body naturally continues in a straight line unless influenced by some Force the second box indicates exactly how Force changes the motion of an object as himself explained change in motion is proportional to the force impressed and it is horses is the word motion to me momentum the velocity of a body X its mass Bobby to express himself using geometric ratio do his laws can be expressed as differential equation 2nd law says that the impressed force is equal to the rate of change of momentum for a body with constant Mass this differential equation reduces to force equals mass times acceleration f equals Ma reaction there is always an equal reaction Laura the mutual actions of two bodies upon each other are always equal and directed to contrary parts this is Newton's third law she cannot touch something else without being touched and return in other words bodies don't merely act with one another at the same time all three of Newton's laws and interact throughout the physical world the trajectory of a powerful and moving back home like to go to Russia allowed to travel freely what's the nature of its trajectory no matter what the projector this purpose could it be understanding arises from an insight into the laws that govern force and motion on Young Thug who is remembered for his legendary confrontation Nation ship between force and momentum David and Goliath is this the model of devastating David managed to demonstrate Force momentum expertly how to help of Aristotle obey the laws of gravity that works perfectly well. understood Newton's Laws does not change the way the world works but they change forever the way in which it's understood it's on the field of battle and Athletics are the green fields of England the Panthers described in the field of mathematics in Newton's own words learn from these photos I deduce the Motions of the planets the comments the moon in the sea wasn't the first to ponder the path of a flying object on earth or that of one of the heavens but he's in his knowledge that the same laws still Galileo Galilei describe projectile motion perfectly he realized bodies can fall vertically horizontally at the same time from Galileo's point of view and everything from the Heavens to the Renaissance bodies motion has two components completely independent of each other Galileo's extraordinary vision is explained equation the vertical component of the vector force is mg downward or - G no Force at all acts in the horizontal Direction medical component of acceleration is - G in the horizontal Direction where there is no Force the acceleration is zero acceleration is the rate of change of since the horizontal speed is not changing must be constant constant speed in a horizontal Direction and constant acceleration downward both acting independently and simultaneously these are the elements of Galileo's trajectories and they're also the results equation Force equals mass times acceleration f equals Ma I do understand the ongoing significance of f equals Ma it's necessary to return to a time before Scholars had as ancient Greece scholars believe everything the nature of all living things according to the Aristotelian all moving objects when the Mover couldn't be seen as in the case of projectile motion Aristotle what was responsible for the movie much later even though Europe in the Middle Ages to explain the underscore the motion of objects such as Spears arrows and cannonballs Scholars came up with the idea of him launching a projectile object stupidest was consumed the object suddenly dropped her impetus wasn't a bad idea short of its Target parabolic path of a real projector was discovered by Galileo in Galileo's words it has been observed some sort however no one has pointed out the fact that this path is a parabola search inside Galleria Roseville world to come to an end and he wasn't alone about the same time Johannes Kepler Christiaan Huygens in another room car in France and others also began to see the universe with new eyes as extraordinary as this collection of scientist was there viewpoints Overlook company an organizing principle the physical world as a whole extraordinary to explain the world it would require the right person in the right place at the right time Righttime 1665 the right person was Isaac Newton at only 23 years of age Newton concede alter forever the world's understanding of the universe just three fundamental law of motion of cars and in doing so mathematical description of motion in other words while Galileo's kinematics describe motion Newton's Dynamics explain it as long as also a buddy move his calculus with his mechanic the motion of a moving object the motion of Akron has an acceleration equal to -2 in the vertical Direction at a constant speed in the horizontal Direction how much the meaning of that costume force behind objects compulsion this Force last only for a moment and determines the shots in the on the shop leaves the Hat which is the value of the horizontal speed have and will continue to have throughout its Journey until the component of velocity changing at a rate equal to -3 derivative of vertical speed with respect to time is minus G not zero ocean has the derivative - G - GT is 1 answer Sgt plus any constant is also an answer since the derivative is there what's the meaning of the constant it's the vertical speed of the object starts out with even if it starts out with a bang mom and dad there is no gravity mini projector would follow a straight line path with both the horizontal and vertical speed with which it started out the motion of a projectile how it is expressed in Galileo's law of falling bodies what really happens is that a projector very straight line pass at a rate equal to 1/2 g t squared just as if it were dropped from rest movies of Galileo consequences Isaac Newton's one concise law summarized in the equation f equals Ma David and Goliath story for you actually I'm David hanging from a tree instead of a train I'm going to get him this one problem I know that at the moment that I pulled the trigger where do I aim in order to hit him while he falls how much do I have to leave them by in order to hit him going to finance it away anyway Hunter would I'm going to write the equations of the projectile I need to know is znx what we know instead is just after sneezing equal to -20 + 301 Xfinity because that's just the x equal to 3 x 9 get square but happy effect of gravity this would be the equation of a straight line it would be a straight line directly from the barrel of a gun so the actual trajectory looks like that provided the gun with him directly at the monkey in the first place just the same one and meet the missile in mid-air and that's what I'm going to do I'm going to shoot down that monkey why are we shooting monkey you can see the other side so the gun is aimed directly at the monkey and now we're ready to shoot him okay I have to tell you that I have practice at the registration many many times okay we're going to do it now everybody ready there we go an equation what an equation is if you ask the average for this in the street what is the most important single equals Ma and there is something very mysterious about that equation accelerate but now I understand what a celebration means what is a PS4 one way to find out it's can use this equation to tell us today in the case of gravity gravity acting on a body at all about how it works equations we don't know the mass of the body show me the maps of the body equation means nothing at all possible is the most important single equation in all of physics look up playing with work this is a problem debated for over 300 years and it was very clear before Isaac Newton wrote this equation down the world with the world of buzzing confusion the world became comprehensible and predictable so whatever else this equation is it certainly isn't meaningless the only way to understand what is equation if I using it and I put the rest of my story is about Force equals mass times acceleration mechanics the science of motion can be summarized in that one equation f equals Ma funding for this program was provided by the atom project to learn more about the Annenberg cpb channel series how to take them
