2) To draw water from a well we have to pull at the rope.
3) An unbalanced force can change an object's motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving.
4) The questioned statement is an example of Gravitational force . When ball strikes the stamps the bails fall down because of the attraction force of Earth toward itself which is Gravitational force .
5) Electrostatics force is responsible for raising our body hairs while taking off a shirt made up of polyester on a dry day. The electrostatic force can be attractive or repulsive in nature that makes it opposite to the gravitational force.
