kinetic and potential energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

How does speed affect kinetic energy?

Back

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

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy is converted into kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What is an example of potential energy?

Back

A pulled back string on an archer's bow is an example of potential energy.

Front

What type of energy is associated with an object at rest?

Back

An object at rest has potential energy.

Front

What is the relationship between kinetic and potential energy in a roller coaster?

Back

As a roller coaster climbs, potential energy increases; as it descends, potential energy converts to kinetic energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).
