• Non-contact force: The force exerted on an object without touching it known as non contact force.
• Gravitational force: the attractive force of earth which acts upon all the objects is called force of gravity or gravitational force.
• Pressure: The force acting on a unit area of a surface is called pressure. It acts perpendicular to the surface on which pressure is exerted.
• Pressure= force/area on which it acts. Lesser the area, greater is the force.
• Both liquids and gases exert pressure on the wall of their containers.
