... The top of a wave is called the crest, and the bottom is the trough. The measurement from crest to crest or trough to trough is the wavelength. The distance the particles in a medium move when a wave passes is the amplitude. The length of time necessary for a wave to pass is the period, and th ...

... The net force acting on an object is the sum of all the forces acting on an object. If two people push in the same direction on a stalled car, each with a force of 25 Newtons, the net force will be 50 Newtons. In a tug of war competition If the net force acting on an object is zero (Fn = 0), The obj ...
