Work and Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has because of its motion.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the chemical bonds of a substance.

Front

How does a bus engine use energy?

Back

A bus engine transfers chemical potential energy into kinetic energy to make the bus move.

Front

Where is gravitational potential energy (GPE) lowest on a roller coaster?

Back

At the lowest point of the roller coaster.

Front

What is mechanical energy?

Back

Mechanical energy is the total kinetic and potential energies in a system.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is the relationship between work and energy?

Back

Work is done when energy is transferred from one system to another.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground.

Front

How is energy conserved in a closed system?

Back

In a closed system, the total energy remains constant; energy can change forms but cannot be created or destroyed.
