Newton's law of motion is the three law of motion. These three law describe the relationship between force acting upon an object.
The three law of motion-
1. First law of motion- this is also known as law of inertia. This law states that An object at rest is remains at rest, and an object in motion is remains in motion at constant speed unless it is acted on by an external force.
For example- pushing any stationary object on table.
2. Second law of motion- The acceleration of an object directly proportional to the mass of the object and the amount of force applied.
Force = mass × acceleration.
For example- if you push the same force to push a truck or car the car will have more acceleration because the car has less mass.
3. Third law of motion- for every action there is an equal and opposite reaction.
For example - a swimmer pushes water backward the water pushes swimmer forward.
