What is newtons law?

Question

I got a question that my dad asked me. So I am wondering what it is

Answer 1

his 3 laws of motion

First law

It is possible to select a set of reference frames, called inertial reference frames, observed from which a particle moves without any change in velocity if no net force acts on it. This law is often simplified into the sentence "A particle will stay at rest or continue at a constant velocity unless acted upon by an external unbalanced force."

Second law

Observed from an inertial reference frame, the net force on a particle is proportional to the time rate of change of its linear momentum: F = d (mv) / dt.[3][4][5][6][7] Momentum mv is the product of mass and velocity. Force and momentum are vector quantities and the resultant force is found from all the forces present by vector addition. This law is often stated as "F = ma: the net force on an object is equal to the mass of the object multiplied by its acceleration."

Third law

Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction. The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence "Every action has an equal and opposite reaction."  

Answer 2

answerer above me has got the right answer

HIS IS COMPLETELY RIGHT

he forgot Newton's Law of Gravitation

F(gravity)=GMm/d^2

this states the force of gravity between 2 oibjects is equal to the product of the two masses and the gravitational constant G divided by the distance squared

G=6.67*10^-11 dyne

M=mass in kg

m=second mass in kg

d^2=distance squared in meters

Answer 3

There are three laws of motion--and a law of gravity.  Ask wiki.
