Forces

Force is a push or pulls acting upon an object as a result of its interaction with another object.

1. Forces can change the speed of an object.

Pushes and pulls are the forces. They have their own directions.

The property of matter due to which it preserves its state of rest or uniform motion is called inertia.

Two or more forces acting at an object can be added or subtracted into a single force known the resultant force.

Balanced and Unbalanced forces are discussed below.

The instrument which is used to measure the weight is called spring-balance or Newton-meter.

If a spring or wire which is fixed at one end is stretched by hanging a load to the other end, then Hooke's law can be defined as:
