newtons laws are based on which two concepts?\no inertia and force\no inertia and gravity\no acceleration…

Brief Explanations:

Newton's first law is related to inertia, which is the tendency of an object to resist changes in its state of motion. Newton's second law relates force, mass and acceleration, with force being a central concept. Gravity is a specific type of force, acceleration and velocity are kinematic quantities, and energy and momentum are different physical - concepts not the basis of Newton's laws.

Answer:

inertia and force
