Potential/Kinetic Energy Review

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy that has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

True/False: Kinetic energy increases as an object speeds up.

Back

True

Front

True/False: Potential energy decreases as an object falls.

Back

True

Front

What happens to potential energy as an object is lifted higher?

Back

As an object is lifted higher, its potential energy increases due to the increase in height.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

If two objects have the same mass, how does height affect their potential energy?

Back

The object at a greater height will have more gravitational potential energy.

Front

What is the relationship between potential energy and kinetic energy during free fall?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

True/False: An object at rest has kinetic energy.

Back

False

Front

What is the effect of mass on kinetic energy?

Back

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