Newton's Laws

First Law (Law of Inertia): An object at rest stays at rest, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced external force.

Second Law (F=ma): The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, which can be represented by the equation F = ma.

Third Law (Action and Reaction): For every action, there is an equal and opposite reaction, meaning that forces always occur in pairs.
