Kinetic and Potential Energy

Front

What type of energy is stored in food?

Back

Potential energy.

Front

How much kinetic energy does a rock with a mass of 3kg have if it has 3J of kinetic energy?

Back

3J.

Front

At which point does a diver have the greatest kinetic energy and the least potential energy when diving?

Back

At the lowest point of the dive.

Front

What happens to the kinetic energy of a bat when it hits a baseball?

Back

Some of the kinetic energy is transferred to the ball, and some is transferred to the air particles as sound waves.

Front

What is the relationship between the speed of an object and its kinetic energy?

Back

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

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

Define potential energy.

Back

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

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

Give an example of potential energy.

Back

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