Question

What is the Newton's three laws of motion?

Answer 1

Hey there

Newton's First Law of Motion, or the Law of Inertia, states that "every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." This means that there is a natural tendency for a moving object to keep moving, unless an external force interferes.

According to the Second Law of Motion, acceleration is produced when a force acts on a mass. The greater the mass, the greater the amount of force required. Force equals mass times acceleration.

The Third Law of Motion states that for every force, there is a reaction force that is equal in size, but opposite in direction. Therefore, whenever one object pushes another object, it gets pushed in the opposite direction equally as hard.

Answer 2

Newton's first law: a body in rest or uniform motion,continues to be in its state until an external force acts on it.

Simply: If net force on a body is zero then the body continues to be in its state and it's acceleration is zero.

Newton's Second Law: The law defines a force to be equal to change in momentum per change in time.

A velocity change occurs when a body is subjected to external force

Velocity change or acceleration depends on the mass of the body

So: F=m*a

Newton's third law : For every action in universe there exists an equal and opposite reaction

This law states that force can never exists single. It always exists in Action-reaction pair

A general example: The thrust of rocket applies force on the launchpad so launchpad exerts equal amount of force on the rocket and rocket moves up

Thus First law : What is force?
Second law : Defines the force
Third law: Application of force
