What are the four laws of physics? PS newton's laws of physics.?

Answer 1

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

III. For every action there is an equal and opposite reaction.

Answer 2

First Law
An object will stay at rest or move at a constant speed in a straight line unless acted upon by an unbalanced force.

Second law
The rate of change of the momentum of a body is directly proportional to the net force acting on it, and the direction of the change in momentum takes place in the direction of the net force.

Third law
To every action (force applied) there is an equal but opposite reaction (equal force applied in the opposite direction).
Another way of stating Newton's third law, an interaction between two objects, is that, if object A exerts a force on
object B, object B will exert the same magnitude force on A, but in the opposite direction.

Not four Laws as you can see...

4th, getting run down by a moving vehicle will hurt you more than the vehicle.
