Question

What is a force? Explain its absolute and gravitational units. State the relation between

them.​

Answer 1

Force Definition

Force can be defined as a push or a pull on a body. It can bring about a change in the condition of rest or motion of a body.

Force is a vector quantity since it possesses both magnitude and direction.

Absolute unit of force

Newton (N) is the absolute unit of force. 1N = 1kgm/s²

Gravitational unit

The gravitational unit of force is kilogram-force (kgf). 1 Kgf is the amount of force on a body of mass 1 kg due to gravity.

Relation between absolute and gravitational unit of force:-

The value of g is approximately 9.8 m/s²

Hence, 1 kgf = 9.8 N

Answer 2

Answer:

Force: Push or pull of an object is considered a force. example: to open a door, either we push or pull it. A drawer is pulled to open and pushed to close.

Absolute system of unit: A system of physical units (as cgs units) based on a unit of a force independent of the value of the acceleration of gravity.

Gravitational system of units: A system of physical units based upon a unit of force that is the weight of a unit mass under a specified standard of gravity.

For example, the Absolute unit of force is Newton (N) and the gravitational unit of force is kilogram weight (kg wt).

1 kg wt = 9.8 N
