Momentum
recently in physics we have been learning about momentum. Momentum is a function of the mass of an object multiplied by its velocity. Therefore the heavier an object is and the faster it is moving the greater its momentum. i noticed this the other day wen for conditioning we were throwing medicine balls. I noticed that the heavier the ball the greater the force of impact was when i caught it. I also noticed that the ball when thrown harder had more force. These conclusions all made sense to me but the lightbulb really clicked wen i noticed that when a lighter ball was thrown faster it had an impulse equal to that of the slower heavier ball.
