Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion; the faster an object moves, the more kinetic energy it has.

What happens to a liquid when a large amount of thermal energy is removed?

Back

The atoms in the liquid lose kinetic energy, causing it to freeze and change to a solid.

Front

What is an independent variable?

Back

The variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with mass; if two objects are moving at the same speed, the heavier object has more kinetic energy.
