A puck traveling at 6 m/s in the + x direction hits a wall and bounces back. Right after the collision with the wall it is traveling in the - x direction at 6 m/s.

Sunlight, wind, and running water are essentially "free." Yet renewable energy sources are a very small part of our energy consumption. Why is this?

If a force of 40 newtons moves a cart a distance of 9 meters, the work done is Nm. If the same force moves the same cart three times that distance, the work done is Nm. NextReset
