Who Sir Issac Newton was

Issac Newton was born is 1642.  He went to the Univercity of Cambridge in England.  He later became a highly respected proffeser there.  Issac never got married.  He had many personalitys such as:  secretive, cryptic and generous to some people he liked, but not others. Sir Issac Newton spent most of his life studing on 3 topics: Laws of motion, laws of planetary motion and calculus.

All 3 laws listed below are about forces and inertia.

law 1

Newtons first law was about forces and inertia.   It states:  a body that is in rest will stay at rest and a body at a constant velocity wil stay doing this indefinitly.

law 2

Newtons second law states that: When a forces in applied on an object, it will accelerate.  the acceleration is in the same direction as the force.  the formula for this is: a(acceleration)=f(force)/m(mass) or it can also be written as f=m a or more accuretly f=ma.

law 3

Newtons trird law talks about the reaction to a force.  it states:  "for every action there is an equal and opposite reaction.".  this means that for every force, there is a second and equal force and that forces always come in pairs.

What a force is:

What inertia is:

Inertia is the internal resistance to change.  An example to explain this would be if an astronaut was in space and was moving a 1 ton satelite, to him it would seem weightless but the satelite would move very slowly.

A force increases or decreases the velocity of a body or object or simply to accelerate.
