what is newton first law second law and third law
Answers
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. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Answer :-
✏ Newton's First Law of Motion - Every body continues in its state of rest or of state of uniform motion in a straight line unless it is compelled by some external force to change that state.
✏ Newton's Second Law of Motion - The rate of change of linear momentum of a body us directly proportional to the applied force and the change takes place in the direction of the applied force.
✏ Newton's Third Law of Motion - To every action, there is always an equal and opposite reaction.
★ More to know :-
• Newton's First Law defines Inertia : According to Newton's first law of motion, every body continues in its state of rest or uniform motion unless an external force acts upon it. This shows that a body, by itself, cannot change its state of rest of uniform motion.
• Newton's Laws of Motion : Sir Isaac Newton (1642 - 1727) made a systematic study of motion and extended the ideas of Galileo. He arrived at three laws of motion which are called Newton's Laws of Motion.
