Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy (KE) is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

How does mass affect Kinetic Energy?

Back

As mass increases, Kinetic Energy increases, assuming velocity remains constant.

Front

How does velocity affect Kinetic Energy?

Back

As velocity increases, Kinetic Energy increases. This relationship is quadratic, meaning if velocity doubles, KE increases by a factor of four.

Front

What happens to Kinetic Energy when velocity decreases?

Back

When velocity decreases, Kinetic Energy decreases.

Front

What is the relationship between speed and Kinetic Energy?

Back

Kinetic Energy increases as speed increases.

Front

Where is Kinetic Energy greatest in a moving object?

Back

Kinetic Energy is greatest when the object is moving the fastest.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for Kinetic Energy is KE = 1/2 mv².

Front

If an object has a mass of 2 kg and is moving at a speed of 3 m/s, what is its Kinetic Energy?

Back

KE = 1/2 * 2 kg * (3 m/s)² = 9 Joules.

Front

What is the unit of measurement for Kinetic Energy?

Back

The unit of measurement for Kinetic Energy is Joules (J).

Front

Can two objects with different masses have the same Kinetic Energy?

Back

Yes, two objects can have the same Kinetic Energy if their mass and velocity are such that KE = 1/2 mv² is equal for both.
