Nota Fizik: Newton's Three Laws of Motion

Newton's First Law

An object at rest continues its states of rest and a moving object will continue
to move with a constant velocity unless acted upon by an external force.

or

A body continues to be in the state of rest or uniform motion in a straight line path unless an external force is applied.

Newton's Second Law

The rate of change of momentum of an object is directly proportional to the resultant force acting on it and is in the direction of the force.

Newton's Third Law

Every action has an equal and opposite direction.


This is the simplified version of Newton's Three Laws of Motion Explanation. It may give you mark but not full marks.

The first law is defective



it should be:
A body continues to be in the state of rest or uniform motion in a straight line path unless an external force is applied.

3rd law "Every action has a reaction that is equal in magnitude but opposite in direction..
