CBSE Class 9 Science Chapter 9 - Force and Law of Motion
Brief Information: This chapter explains the 3 laws of motions with the help of diagrams and examples. Below are the 3 laws of motions:
- First law of motion: An object continues to be in a state of rest or of uniform motion along a straight line unless acted upon by an unbalanced force.
- Second law of motion: The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force.
- Third law of motion: To every action, there is an equal and opposite reaction and they act on two different bodies.
