Answer 1

1. The following actions are seen:
   1. Lifting a school bag.
   2. Pushing a wheel with a stick.
   3. Hammering a nail.
   4. Carrying a heavy log.
   5. Pressing a sponge with a finger.
   6. Pulling a box with a rope.
   7. Stretching a bow to shoot an arrow.
2. Yes. Force is being applied in every action. The force may be in the form of a push, pull, lift, press or stretch.
3. In most of the actions, the object changes its original position because of the applied force. For example, the bag is lifted, the wheel rolls, the nail moves into the surface, the log is carried and the box is pulled. In some actions, such as pressing the sponge or stretching the bow, the force mainly changes the shape of the object.
