Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object due to its motion. It depends on the mass and speed of the object.

Front

How does speed affect Kinetic Energy?

Back

Increasing an object's speed increases its kinetic energy.

Front

How does mass affect Kinetic Energy?

Back

If moving at the same speed, increasing an object's mass will increase its kinetic energy.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

Which has more Kinetic Energy: a moving car or a stationary car?

Back

A moving car has more kinetic energy than a stationary car.

Front

If two objects are moving at the same speed, how do you determine which has more Kinetic Energy?

Back

The object with greater mass will have more kinetic energy.

Front

What happens to Kinetic Energy if an object's speed doubles?

Back

If an object's speed doubles, its kinetic energy increases by a factor of four.

Front

What is an example of Kinetic Energy in everyday life?

Back

A rolling ball, a flying airplane, or a running person are all examples of kinetic energy.

Front

Where is Kinetic Energy greatest in a tossed baseball?

Back

The kinetic energy of a tossed baseball is greatest at the point where it is moving the fastest.

Front

What type of energy is Kinetic Energy often compared to?

Back

Kinetic Energy is often compared to Potential Energy, which is stored energy based on an object's position.
