Accepted Answer

A force that does not need a connector - Non contact force.

A non-contact force is one that works on an object without actually coming into touch with it. Gravity, which provides weight, is the most well-known non-contact force. A contact force, on the other hand, is a force that acts on an object that comes into actual touch with it.

The force required to raise $100 g$ mass, vertically upward against gravity - newton.

The unit of force in the meter-kilogram-second system equal to the force required to impart an acceleration of one meter per second to a mass of one kilogram.

A force which cannot be applied through a non-rigid connector - Push.

A push is a force that causes an object to move from its resting position. When you push anything, it tends to move away from you. Push force is demonstrated by kicking a ball, closing a door, pushing a trolley, and inserting a plug into a socket.

SI unit of pressure - pascal.

The SI unit of pressure is pascal which is equal to one newton per square metre.

Approximate pressure exerted by air - $100 k Pa$ .

The atmospheric air exerts a force on all the objects in the atmosphere and on the earth. The force or thrust exerted by the atmospheric air on a unit area is defined as atmospheric pressure.

Common name for liquids and gases - Fluids.

A fluid is any substance that is able to flow.
