drop of the egg has many physics, when the egg drops there it has lost for forces behind it such as the eggs speed and the movement of it. The forces of the egg is velocity, speed, Newton's first law, gravity and acceleration. If you see when the egg drops the motion will still remain moving until it gets interrupted by any other other forces, for example the floor that the egg would eventually hit would be the force that causes it to stop it from moving.
