What is Kinetic Energy?

Back

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

What is the formula for calculating Kinetic Energy?

Back

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

How does mass affect Kinetic Energy?

Back

Increasing the mass of an object increases its Kinetic Energy if the velocity remains constant.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more Kinetic Energy it has, since Kinetic Energy is proportional to the square of the velocity.

Front

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

Back

If an object's speed doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.

Front

Can an object have Kinetic Energy if it is not moving?

Back

No, an object must be in motion to have Kinetic Energy. A stationary object has zero Kinetic Energy.

Front

What is an example of an object with Kinetic Energy?

Back

A tennis ball rolling across the court has Kinetic Energy due to its motion.

Why is it harder to stop a heavier moving object compared to a lighter one?

Back

A heavier object has more Kinetic Energy at the same speed, making it harder to stop.

Where is Kinetic Energy greatest in a moving object?

Back

Kinetic Energy is greatest at the point where the object is moving the fastest.

What is the relationship between Kinetic Energy and work done?

Back

The work done on an object is equal to the change in its Kinetic Energy.
