What are the 3 laws of physics?

Answer 1

This comes from the Physics Classroom Web site. They say what you call Laws of Physics are actually Newton's Laws of Motion:

The first law of Physics:

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

The second law of Physics:

The acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

The third law of Physics:

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

If the terminology is any difficulty, let me know.
