Hello Midhun,

Sir Isaac Newton's three laws of motion describe the motion of massive bodies and how they interact.

The First Law of Motion states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force." This means that things cannot start, stop, or change direction all by themselves. It takes some force acting on them, externally to cause such a change. This property of massive bodies to resist changes in their state of motion is called inertia .

The Second Law of Motion states, "The force acting on an object is equal to the mass of that object times its acceleration." In mathematical notation, it is written as  F  = m a  , where  F  is force, m is mass, and  a  is acceleration. The law explains what happens to a massive body when it is acted upon by an external force.

The Third Law of Motion states, "For every action, there is an equal and opposite reaction." The law describes what happens to a body when it exerts a force on another body. Forces always occur in pairs and thus when one body pushes against another, the second body pushes back just as hard.

One newton is defined as the force that will accelerate a mass of one kilogram at the rate of one meter per second per second.

Hope this helps you. We wish you the best for your future endeavours!

Hello dear student !

Please elaborate your question clearly more so that we can answer your question properly . MeanwhileIf you are asking about Newton's laws of motion , then, Newton gave 3 laws of motions which is a great contribution in physics.
