Kinetic energy problems

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 0.5 * mass (m) * velocity (v)^2

Front

How much kinetic energy does a moving 6 kg object have if it moves with a velocity of 3 m/s?

Back

27 J

Front

What is the kinetic energy of a 4kg shotput thrown with a velocity of 13m/s?

Back

338 J

Front

A rabbit of mass 3kg walks at a speed of 0.5m/s. Calculate its kinetic energy.

Back

0.375 J

Front

What is kinetic energy?

Back

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

Front

What is the unit of kinetic energy?

Back

Joule (J) is the unit of kinetic energy.

Front

A golf pro swings his driver which weighs 0.75Kg at a velocity of 60 m/s. Calculate the kinetic energy of the club.

Back

1350 J

Front

What happens to kinetic energy if the velocity of an object doubles?

Back

If the velocity doubles, the kinetic energy increases by a factor of four (since KE is proportional to the square of velocity).

Front

What is the kinetic energy of a 10 kg object moving at 2 m/s?

Back

20 J

Front

If an object has a mass of 5 kg and a kinetic energy of 50 J, what is its velocity?

Back

The velocity is 10 m/s.
