Newton's three laws and the Universal Law of Gravitation. In simple terms.?

Answer 1

Newton's :

1st Law -- Every body continues moving or resting unless some
force acts on it.

2nd Law -- When force is applied on body, its change in momentum is directly proportional to force applied n body takes the direction of applied force. (F=ma).

3rd Law -- Every action has an equal n opposite reaction. THIS WORKS IN REAL LIFE TOO. TRY HITTING SOMEBODY THE NEXT TIME N U'LL GET A DEMO OF THIS LAW. It's pretty self-explanatory, though.

Gravitation Law -- Every particle in the universe attracts every other particle with a force, which is given by the formula :
f = GxMxm / r^2, where G=gravitational const (6.67x10^-11), M=mass of 1 body, m=mass of 2nd body, r=dis. between 2 bodies.

Simplest terms i could use...

Answer 2

first and second law :f=ma (for first f=0 so a=0)

third f(ab)= - f(ba)

law of gravitation f=GMm/r^2
