Kinetic EnergyQuiz - Solve & Score
Q1. A car of mass 2 kg is moving at 4 m/s. What is its kinetic energy?
- A.32 J
- B.17 J
- C.16 J
- D.4 J
Answer: C. 16 J
KE = 1/2 * m * v^2 = 0.5 * 2 kg * (4)^2 = 0.5 * 2 * 16 = 16 J.
Q2. What kinetic energy does a football of mass 5 kg carry while travelling at 6 m/s?
- A.38.5 J
- B.15 J
- C.90 J
- D.180 J
Answer: C. 90 J
KE = 1/2 * m * v^2 = 0.5 * 5 kg * (6)^2 = 0.5 * 5 * 36 = 90 J.
Q3. A motorbike weighing 3 kg speeds along at 10 m/s. Calculate the energy stored in its motion?
- A.300 J
- B.15 J
- C.150 J
- D.101.5 J
Answer: C. 150 J
KE = 1/2 * m * v^2 = 0.5 * 3 kg * (10)^2 = 0.5 * 3 * 100 = 150 J.
