What is the name of the man who invented the theory of relativity?
Albert Einstein
Newtons Second Law states what?
Forces is equal to mass times acceleration
A ball is kicked at an angle of 45 degrees above the horizontal with an initial velocity of 20 m/s. Calculate the horizontal velocity.
14m/s

Newtons Third law states?
Every force as an equal and opposite force acted on it.
