U3 GPE and KE ENERGY FLASHCARD

Front

What is the equation for kinetic energy?

Back

Kinetic energy (KE) is given by the equation: KE = ½ x mass x velocity².

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

How does the speed of an object affect its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is gravitational potential energy (GPE)?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.

Front

How do you calculate gravitational potential energy?

Back

GPE = mass x gravity x height.

Front

What is the gravitational acceleration on the Moon?

Back

The gravitational acceleration on the Moon is approximately 1.622 m/s².

Front

What type of energy is associated with motion?

Back

Energy due to motion is called kinetic energy.

Front

What happens to kinetic energy when an object's mass increases?

Back

If the mass of an object increases while its velocity remains constant, its kinetic energy increases.

Front

What is the relationship between velocity and kinetic energy?

Back

Kinetic energy is proportional to the square of the velocity; if velocity doubles, kinetic energy increases by a factor of four.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy is the Joule (J).
