Energy

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground and its mass.

Front

What two factors does gravitational potential energy depend on?

Back

Height and mass.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What happens to a skater going up a ramp?

Back

The skater cannot reach the same height due to friction slowing him down.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What type of energy does a rock at the edge of a cliff have?

Back

Potential energy.

Front

What is the relationship between height and potential energy?

Back

As height increases, potential energy increases.

Front

What is the relationship between speed and kinetic energy?

Back

As speed increases, kinetic energy increases.

Front

What happens to energy when a roller coaster goes over a hill?

Back

Some energy is lost to friction and air resistance, preventing it from reaching the same height.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.
