Physics Mechanics Quiz

Newton's First Law states that an object at rest stays at rest, and an object in motion remains in that state unless acted upon by an unbalanced force, which embodies the concept of inertia.

In the equation F=ma, F represents the net force acting on an object, m is its mass, and a is the acceleration produced as a result of that force.

Displacement is the change in position of an object, defined as the shortest distance between its initial and final positions, unlike distance which is the total path traveled.

<p>Coulomb's Law states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.</p> Signup and view all the answers
