Click on the flashcard to see the answer



What is kinetic energy?

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

What factors influence kinetic energy?

The mass and velocity of an object influence its kinetic energy.

How is kinetic energy calculated?

Kinetic energy is calculated using the formula KE = 1/2 mv^2.

What is gravitational potential energy?

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

Which factors affect gravitational potential energy?

Height, mass, and the gravitational field strength affect gravitational potential energy.

How do you calculate gravitational potential energy?

Gravitational potential energy is calculated using PE = mgh.

What unit is used to measure kinetic and gravitational potential energy?

Both are measured in joules (J).

What happens to kinetic energy when an object's speed doubles?

Its kinetic energy quadruples.

When does an object have the highest gravitational potential energy?

When it is at its highest position above the ground.

Can an object have both kinetic and potential energy?

Yes, an object can have both simultaneously.

What is the law of conservation of energy concerning kinetic and potential energy?
