Kinetic Energy Calculations | GCSE Physics Practice

Kinetic energy is the energy of a moving object. Master the 1/2mv² formula for your exam.

Can you calculate energy when speed is squared?

What is Kinetic Energy Calculations | Practice?

"The energy an object has due to its motion."

Question 1

Which formula is used to calculate kinetic energy?

Question 2

If the speed of a car doubles, what happens to its kinetic energy?

Question 3

An object has a mass of 2 kg and travels at 3 m/s. What is its kinetic energy?

Kinetic energy depends on mass and the square of the speed.

The formula is Ek = 1/2 m v².

Mass is in kg and speed is in m/s.

Exam Tip

Misconception: Students often forget to square the velocity BEFORE multiplying by 0.5 and mass.

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
