What is kinetic energy?
AThe energy stored in a chemical bond
BThe energy an object has from its height
CThe energy an object has from its motion
DThe energy released when a fuel is burned
Answer & Solution
Correct answer: C. The energy an object has from its motion
1. Kinetic energy is possessed by an object because it is moving.
2. Falling water has kinetic energy, which turns generators in a hydroelectric plant.
3. Expanding gases in an engine cylinder carry kinetic energy that moves the pistons.
4. Energy due to height or to stored chemicals is potential energy instead.
