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 speed at which it is moving.

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 energy.

Front

Give an example of kinetic energy.

Back

A wagon rolling down a hill is an example of kinetic energy.

Front

How does kinetic energy transform into potential energy?

Back

Kinetic energy transforms into potential energy when an object moves against a force, such as when a ball is thrown upwards.

Front

What is the relationship between kinetic and potential energy?

Back

Kinetic and potential energy are forms of mechanical energy. They can transform into each other; for example, as an object falls, potential energy converts to kinetic energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, calculated as weight times height.

Front

What is an example of potential energy?

Back

A car parked at the top of a hill has potential energy due to its height.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for gravitational potential energy?

Back

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