NEWTON'S LAW OF MOTION
Newton was the first to formulate the laws of motion known as "newton's law of motion".There are three laws of motion that we'll discuss now
- First law of motion
- Second law of motion
- Third law of motion
NEWTON'S FIRST LAW OF MOTION
First law of motion deals with bodies which are either at rest or moving with uniform speed in a straight line.According to newton's first law of motion,a body at rest remains at rest provided no net force acts on it.This part of the law is true as we observe that objects do not move by themselves unless someone moves them .For example, a book lying on a table remains at rest as long as no net force acts on it.
Similarly, a moving object does not sop moving by itself .A ball rolled on rough ground stops earlier than that rolled on a smooth ground.It is because rough surfaces offer greater.If there would be no force to oppose the motion of a body then the moving body would never stop,Thus Newton's law of motion states that:
"A body continues it's state of rest or of uniform motion in a straight line provided no net force acts on it."
Since Newton's first law of motion deals with the inertial properties of matter,therefore,Newton's first law of motion is also known as "Law of inertia".
second are third laws are coming at night.....please subscribe for more science stuff.
