FORCE》

FORCE is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the application of force is the point where force is applied.

The Force can be measured using a spring balance.

The SI unit of force is Newton(N).

Examples of pushing

i) Pushing a heavy block to displace it from its original position.

Examples of pulling:

i) Drawing a bucket of water from a well.

i) Drawing a bucket of water from a well.ii) Opening a drawer of a table.

Examples of Non-Contact Forces are:

Gravitational force.

Gravitational force.Magnetic force.

Gravitational force.Magnetic force.Electrostatics.

Gravitational force.Magnetic force.Electrostatics.Nuclear force.

Examples of Contact Forces are:

1.frictional forces

2.tension forces,

3.spring forces

Answer 2

Answer:

The force of the explosion knocked them to the ground.

(i) Push: We close drawer by pushing.

We move a wooden box by pushing.

(ii) Pull: We draw water from a well by pulling the rope.
