Answer: 1) The force arises due to gravitational or electrostatic pull/push between two objects.
2) Gravitational force, Magnetic force, Electrostatics, nuclear force
3) magnitude
4) it can change the state of rest or motion of a particular body
5) muscular force
6) opposite to that of the object in motion
7) Pressure
Q2
1) zero and no movement
2) Why it is easy to cut with a sharp knife than a blunt? The pressure exerted by the sharp knife edge is more than that exerted by the blunt one because the area on which force is exerted with a sharp knife is very small. Thus, it is easier to cut with the former than with the latter.
3) Porter place a round piece of cloth on their heads when they have to carry heavy loads to increase the area on this head. Hence, the pressure on the head gets reduced. As P = area force
