A ball is dropped from a certain height. t₁ is just before it is dropped and t2 is just before it hits the floor. The system is just the ball A ball is dropped from a certain height. t₁ is just before it is dropped and t2 is just before it hits the floor. The system is just the ball and the Earth A wooden block at rest on a rough surface is pushed so that it moves at constant speed. t₁ is at the beginning when it is moving and t2 is at the end when it is still moving. The system is the block, the surface and the Earth. A wooden block at rest on a rough surface is pushed hard enough that it speeds up. t₁ is at the beginning when it has a speed of 0, t2 is when it has reached a certain speed. The system is the block, the surface and the Earth.
