[Music] Newton's second law of motion you all know it but as we delve deeper into Newtonian mechanics I need you to more than know it I need you to be able to see it so when I ask what is acceleration don't immediately think numbers instead close your eyes and imagine a ball being shot across the sky now imagine an identical ball in outer space racing with the ball on earth with the same force applied which ball would win a race you don't need to raise your hand to speak here of it oh really well the ball in outer space would win because it's traveling in a vacuum I have another question go on well now I'm imagining that the ball is traveling in deep space there's no stars or planets around it acceleration is the derivative of velocity with respect to time how do you know that the ball is moving at all if there's nothing to compare its motions to in other words butthis time and for that matter at his space Newton's Principia Volume one absolute true and mathematical time of itself and from its own nature flows equitably without relation to anything external time and space absolute I know then let's move on but when pressed on the subject of absoluteness Newton said the date he enjoys forever and by existing always and everywhere constitutes duration and space which in short is saying I have no idea but God must so that Albert I know I should I should sit down well it looks like we are going to have an interesting year [Music]
