Forces, A push or pull acting upon an object., Net Force, The total combination of all individual forces acting on an object at the same time, Inertia, The tendency of an object to resist a change in its motion, Speed Formula, Speed = Distance ÷ Time, Weight, The force exerted on an object due to gravity, Newton’s 2nd Law of Motion, An object’s mass directly affects how much force is needed to accelerate (measured in meters per second squared) the object., Law of Universal Gravitation, Newton’s Law of Universal Gravitation states that every particle attracts every other particle in the universe with force directly proportional to the objects mass, Unbalanced Force, Occurs when the total forces acting on an object do not cancel each other out., Balanced Force, When two or more forces acting on an object are equal in strength but opposite in direction., Acceleration, The rate at which an object changes its velocity, Mass, The actual amount of matter (atoms and molecules) in an object. It is constant and does not change based on your location in the universe., Newton’s 1st Law of Motion, An object at rest remains at rest, and an object in motion stays in motion, unless acted upon by an unbalanced force, Newton’s 3rd Law of Motion, For every action, there is an equal and opposite reaction, Gravity, An invisible force of attraction that pulls objects toward each other
