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.
