Energy and Motion

Front

What is potential energy?

Back

The energy an object has due to its position.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is total energy?

Back

The sum of potential energy (PE) and kinetic energy (KE) in a system.

Front

How does potential energy change when an object is lifted?

Back

Potential energy increases as the object is lifted higher.

Front

What happens to kinetic energy when an object speeds up?

Back

Kinetic energy increases as the object's speed increases.

Front

What is the relationship between potential energy and kinetic energy in a falling object?

Back

As potential energy decreases, kinetic energy increases.

Front

What determines the amount of potential energy in a stretched rubber band?

Back

The amount of potential energy is determined by how much the rubber band is stretched.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car or a running dog.

Front

What happens to total energy when an object moves from a higher position to a lower position?

Back

Total energy remains constant; it transforms between potential and kinetic energy.

Front

What is the effect of mass on kinetic energy?

Back

Kinetic energy increases with greater mass if speed remains constant.
