Question

Write and explain all 3 laws of motion.​

Answer 1

Answer:

Newton's first law of motion :-

It states that, an object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀Or

An object continues to be in the state of rest or of uniform motion along a straight line unless acted upon by an unbalanced force.

Newton's second law of motion :-

It states that, the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.

Newton's third law of motion :-

It states that, when one object exerts a force on other object, second object ínstantaneously exerts a force back on the first.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀Or⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

To action there is an equal and opposite reaction.

Answer 2

Newton's first law: the law of inertia

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. ... This postulate is known as the law of inertia.

Newton's second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ... Newton's second law is one of the most important in all of physics.

Newton's third law: the law of action and reaction

Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
