Energy A1-5

Front

What does the law of conservation of energy state?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What happens to kinetic energy as the speed of an object increases?

Back

The kinetic energy increases.

Front

Which of the following has kinetic energy? A car parked on a hill, a tennis ball rolling, a picture on the wall, a piece of coal before burning?

Back

A tennis ball rolling across the court has kinetic energy.

Front

What are the two things that conservation of energy states energy cannot be?

Back

Created or destroyed.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

At the lowest point of the swing.

Front

Define kinetic energy.

Back

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

Front

What is potential energy?

Back

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

Front

Give an example of potential energy.

Back

A book on a shelf has potential energy due to its height.

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 the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass if velocity is constant.
