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 Essentials
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.
Want to improve faster?
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.
