What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically calculated as the product of mass, gravitational acceleration, and height above a reference point.

What energy transformations occur when a battery-operated radio is in use?

Back

Chemical energy is transformed into electrical energy, which is then transformed into sound energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as one-half the mass of the object multiplied by the square of its velocity.

How does height affect gravitational potential energy?

Back

As height increases, gravitational potential energy increases, assuming mass remains constant.

What is the formula for calculating gravitational potential energy?

Back

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