This memory aid covers Memory Aid: The KE Equation within Kinetic Energy for GCSE Physics. Revise Kinetic Energy in Energy for GCSE Physics with 15 exam-style questions and 30 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 11 of 15 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 Memory Aid: The KE Equation
Remember E_k = ½mv² with this sequence: "Half My Velocity Squared"
Half = the ½ | My = m (mass) | Velocity = v | Squared = the ² superscript
For the v² effect, think of road safety: "Double the speed, four times the danger." This locks in the squared relationship without even needing the formula.
Practice questions for Kinetic Energy
Which of the following objects has kinetic energy stored in its kinetic energy store?
A car travels at 20 m/s. The driver then doubles their speed to 40 m/s. Explain what happens to the kinetic energy of the car and by what factor it changes.
