Which one of these has kinetic energy?
AA stone on a wall
BA bird in flight
CA book on a shelf
DA parked bicycle
Answer & Solution
Correct answer: B. A bird in flight
1. Kinetic energy is the energy an object has because it is moving.
2. A bird in flight is moving, so it has kinetic energy.
3. A stone on a wall, a book on a shelf and a parked bicycle are all still.
4. Those three have stored energy but no kinetic energy.
