What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically measured relative to the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the unit of energy?

Back

The unit of energy is the joule (J).

Front

How do you calculate gravitational potential energy?

Back

Gravitational potential energy can be calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula a = (final velocity - initial velocity) / time.

Front

What is the relationship between work and energy?

Back

Work is done when energy is transferred from one system to another, and it is equal to the energy transferred.

Front

What is the formula for work?

Back

Work can be calculated using the formula W = Fd, where W is work, F is force, and d is distance.
