Terminal Velocity
... The accelerating force acting on all falling objects is gravity – all objects would fall at the same rate if there was no drag (air resistance) The drag is due to the area and shape of the object, which determines the terminal velocity – in skydiving the force of weight = mass x gravity pulls th ...

... Law of conservation of momentum: when no external forces act on a system consisting of 2 objects, the total momentum of the system before the collision = the total momentum of the system after the collision. Example: A baseball player uses a pitching machine to help him improve his batting average. ...
