An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

For every action, there is an equal and opposite reaction.

The product of the force applied to an object and the distance the object moves in the direction of the force.

The capacity to do work.

The rate at which work is done.

The product of an object's mass and its velocity.

The change in momentum of an object when it is subjected to a force over time.

The interaction between two or more objects where they exchange momentum and energy.

The angle through which a point or line has been rotated in a specified sense about a specified axis.

The rate of change of angular displacement with respect to time.

The rate of change of angular velocity with respect to time.

The measure of the force that can cause an object to rotate about an axis.

Every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

The region of space around a mass where another mass experiences a force of attraction.

The motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke's Law.

A disturbance that travels through a medium from one point to another.

The study of fluids at rest.

The study of fluids in motion.
