Physics Concepts

Velocity = Rate of change of an object's position with respect to a frame of reference Acceleration = Rate of change of velocity of an object over time Force = An interaction that causes a change in motion of an object Inertia = Tendency of an object to resist changes in its state of motion

Newton's First Law = An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force Newton's Second Law = The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object's mass Newton's Third Law = For every action, there is an equal and opposite reaction Law of Universal Gravitation = Every point mass attracts every single other point mass by a force pointing along the line intersecting both points

Acceleration = Meter per second squared (m/s^2) Force = Newton (N) Mass = Kilogram (kg) Velocity = Meter per second (m/s)
