Newton's First Law

Also known as the Law of Inertia, it states that an object will remain at rest or move at a constant velocity v unless acted upon by a net external force. This implies that if the net force is 0, the acceleration a is also 0.

Newton's Second Law

This law states that the acceleration a of an object is directly proportional to the net force F and inversely proportional to its mass m. This relationship is defined by the equation F = m a.

Newton's Third Law

This law states that for every action, there is an equal and opposite reaction. If object 1 exerts a force on object 2, then object 2 exerts a force of equal magnitude and opposite direction back on object 1.

Law of Universal Gravitation

The gravitational force F between two masses m{1} and m{2} is proportional to the product of their masses and inversely proportional to the square of the distance r^{2} between them: F = G \frac{m{1} m{2}}{r^{2}}, where G is the gravitational constant.
