There is a difference in the way we use the term ‘work’ in day-to-day life and the way we use it in science. True False 2. Activities like playing in a field, talking with friends, humming a tune, watching a movie, attending a function are sometimes considered to be work from science point of view. True False 3. Push a pebble lying on a surface. The pebble moves through a distance. You exerted a force on the pebble and the pebble got displaced. In this situation work is done. True False 4. Work done = mass × displacement True False 5. Work has only magnitude and no direction. True False 6. 1 J is the amount of work done on an object when a force of 1 N displaces it by 1 m along the line of action of the force. True False 7. Nm and J have same meaning. True False 8. The Sun is not the biggest natural source of energy to us. True False 9. When a hammer is placed at a height, and it start to fall the kinetic energy will change into potential energy. True False 10. The unit of energy and work is same. True False 11. A moving object can do work. True False 12. An stationary object at some height can do work. True False 13. An object moving faster can do more work than an identical object moving relatively slow. True False 14. Objects in motion donot possess energy. True False 15. Kinetic energy is the energy possessed by an object due to its position. True False 16. Kinetic energy of a body moving with a certain velocity is equal to the work done on it to make it acquire that velocity. True False 17. You transfer energy when you stretch a rubber band. The energy transferred to the band is its potential energy. True False 18. An object decreases its energy when raised through a height. True False 19. The form of energy can be changed from one form to another. True False 20. The law of conservation of energy states that the total energy before and after the transformation remains the same.
