Also known as the law of inertia
Newton's first law of motion states that: “An object in motion will remain in motion and an object at rest will remain at rest unless acted upon by a force”. An example of this law is throwing balls: A light beachball will require a lot less force to move than a heavy bowling ball.
Second Law of Motion
Example:
It is easier to push an empty cart in a supermarket than it is to push a loaded one. More mass requires more force to accelerate.
Third law of motion
Example:
A swimmer pushes the water backward by his/her hands and in return the water pushes the swimmer forwards, thus enabling him to go forward during swimming.
