Simple machines are designed to increase A) gravity B) friction C) force D) mechanical advantage

Conserving energy makes which type of energy last longer?

A kiddie roller coaster car has a mass 100 kilograms. At the top of a hill, it's moving at a speed of 3 meters/second. After reaching the bottom of the hill, its speed doubles. The car's kinetic energy at the bottom is its kinetic energy at the top.

Acceleration occurs when an object changes
