Write newton's laws of motion and their limitations also
Answers
If the total force acting on a body is zero, then it travels in a straight line at constant speed. ... Newton's third law: To every action there is always opposed an equal and opposite reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts
Answer:-
First law of motion:-
First law of motion states that if an object is remains at state of rest or of uniform motion, it will at the rest only unless acted by an external unbalanced force.
Second law of motion:-
Second law of motion states that the rate of change in momentum of an object is proportional to the unbalanced force.
Third law of motion:-
Third law of motion states that the every action, there is an equal and opposite reaction and they act on each other or two different bodies.
Limitations of Newton's law:-
⇒ Netwon’s laws of motion only apply to inertial frames, which are the frames obey the Newton's first law.
⇒ They are inexact under all conditions and possible fames.
⇒ Newton’s third law we learn that a unit force is simply the direction of the interaction between two bodies
⇒ Newton's second law is not possible in non-inertial frames, and the third law is violated in relativity.
