Newton's laws of motion

Newton's Laws of motion

Sir Isaac Newton was one of the greatest scientists and mathematicians that ever lived.Born in England on December 25, 1643.
He stdied in Trinity College Cambridge.While at college he became interested in math, physics, and astronomy. Newton received both a bachelors and masters degree.
Newton had ideas about gravity, the diffraction of light, and forces.
He died at the age of 87, but before that he proposed the most popular theory "Newton's laws of motion"
Newton's laws of motion(1st law)
1st newton's laws of motion stats that everybody in the universe continues its state of rest or motion until and unless an external force is applied on it. This newton's laws of motion says that if a ball is kicked and if their is no force to stop then it will never stop and go round and round the earth. A moving car can revolve round the earth if no brakes a re applied.
But this doesnt happen because of opposing forces such as frictional forces and gravitational forces and other opposing objects such as stones bricks etc.
Newton's laws of motion (2nd law)
We know about speed. But this Newton's laws of motion talks about acceleration.
Acceration of a body is defind as the ability of the body to gain speed at a particular time. That means if a body has accelaration 10m/s(i/e Meters travelling per second) then every second its speed increases by 10m/s.
Ths Newton's laws of motion says that greater the mass or weight of the body greater will be the force needed for it to move.
For example more force will be needed to kick a light ball, but greater amount of forece will be needed to move a wall.
Newton's laws of motion(3rd law)
This Newton's laws of motion states that to every action there is an equal and opposite reaction.
Simply if we open up a filled ballon then ballon moves in the direction opposite to the flow of air.This is as the walls of the ballon pushes the air out of the ballon, the air also pushes the ballon away from it.
This newton's laws of motion is applicable to all body in the universe.
