Kinetic enery formula practice

Physical Science - Science

  1. Read each problem carefully.

  2. Use KE = ½ × mass × speed². Rearrange the formula when finding mass or speed.

  3. Use mass in kilograms (kg), speed in metres per second (m/s), and kinetic energy in joules (J).

  4. Calculators are allowed. Remember to square the speed!

  5. Show your working on paper and enter your final answers in the boxes. If units are already provided, enter numbers only.

  6. Check your answers, then click Finish.
