Kinetic Energy

Front

What is Kinetic Energy?

Back

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

Front

What is the formula for Kinetic Energy?

Back

KE = 1/2 * m * v², where m is mass and v is velocity.

Front

What is the unit for Kinetic Energy?

Back

Joules (J) is the unit for Kinetic Energy.

Front

What is the unit for mass?

Back

Kilograms (kg) is the unit for mass.

Front

What is the unit for velocity?

Back

Meters per second (m/s) is the unit for velocity.

Front

If a 1 kg bird flies at 4 m/s, what is its Kinetic Energy?

Back

8 J.

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with greater mass, as it is directly proportional to mass.

Front

How does velocity affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the velocity, meaning if velocity doubles, KE increases by four times.

Front

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

Back

The Kinetic Energy is reduced to one-fourth of its original value.

Front

Calculate the Kinetic Energy of a 1,000 kg sports car moving at 200 m/s.

Back

20,000,000 J.
