Issac Newton's laws of motion.

Newtons 1st Law

Also known as the law of inertia, Newton's 1st Law states that an object at rest will remain at rest and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Newtons 2nd Law

describes the relationship between force, mass, and acceleration, stating that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Newton’s 3rd Law

States that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs, with one force acting in one direction and the other acting in the opposite direction.

Intertia

the property of an object to resist changes in its state of motion.
