Question

what is newton's law of motion?​

Answer 1

Answer:

Explanation:

There are 3 Newtons laws of motion  !

FIRST LAW OF MOTION

Every body maintains its initial state of rest or motion with uniform speed on a straight line unless an external force applied on it.

First law is also called LAW OF GALILEO OR LAW OF INERTIA.

EXAMPLES OF INERTIA

• When a car starts suddenly , the passenger bends backward.
• when running horse stops suddenly , the rider bends forward.
• When a coat or blanket is beaten by a stick , the dust particles are removed.

FIRST LAW GIVES the definition of force.

FORCE - It is a external cause that forces the body to change its initial state of body.

NEWTON’S SECOND LAW

The rate of change in momentum of a body is directly proportional to the applied force on the body and takes place in direction of force.

NEWTON’S SECOND LAW GIVES THE MAGNITUDE OF FORCE.

NEWTON’S FIRST LAW CONTAINED IN THE SECOND LAW.

NEWTON’S THIRD LAW

To every action there is equal and opposite reaction.

FOR INSTANCE

• Recoil of a gun.
• Motion of a rocket.
• Swimming
• while drawing water from well.

Hope it helps ☺️... please Mark As Brainliest

Explanation:

Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration.
