Front

A 6kg cat misjudges a jump and falls 5 meters. How much gravitational potential energy does the cat have before they jump? (Use PE = mgh, g = 9.81 m/s²)

Back

294 J

Front

Define potential energy.

Back

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

Front

What is the formula for kinetic energy?

Back

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 because of its position in a gravitational field, calculated as PE = mgh.

Front

What does 'm' represent in the potential energy formula PE = mgh?

Back

'm' represents the mass of the object.

Front

What does 'g' represent in the potential energy formula PE = mgh?

Back

'g' represents the acceleration due to gravity, approximately 9.81 m/s² on Earth.
