kinetic energy

Front

What is kinetic energy?

Back

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

Front

What two factors affect an object's kinetic energy?

Back

Mass and speed.

Front

As the velocity of an object decreases, what happens to its kinetic energy?

Back

It decreases.

Front

As mass increases, what happens to kinetic energy?

Back

It increases.

Front

True or False: Increasing an object's speed will increase its kinetic energy.

Back

True.

Front

What is the formula for calculating kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

If a car is moving faster, what happens to its kinetic energy?

Back

It increases.

Front

If two objects have the same speed, which one has more kinetic energy?

Back

The one with more mass.

Front

What unit is kinetic energy measured in?

Back

Joules (J).

Front

If an object is at rest, what is its kinetic energy?

Back

0 Joules.
