Newton’s First Law of Motion Class 9 | Law of Inertia


Newton’s First Laws of Motion { Law of Inertia }- It states that a body continue in its state of rest or of uniform motion until it is comepelled by any external unbalance forces.

This laws is also known as law of inertia.

Inertia is the proerty of a body which cause it to maintain its state of motion or rest.

Unbalanced Forces : When two unequal forces acts on an object and the object change its state then we say that the forces are unbalance.
Unbalance forces can be understood from example of tug of war.
