Inertia The tendency of an object to resist change in motion. Newton’s Second Law Acceleration of an object depends on the mass of the object and the amount of force applied. Velocity has both speed and direction of an object in motion. Calculating Speed Speed = distance time Slope Slope = Y2 Y2 X2 X1 Friction The force that two surfaces exert on each other when they rub against each other. Gravitational Force The force that pulls objects towards each other. Mass The measure of the amount of matter in an object. Weight The force of gravity on a person or object at the surface of a planet. Air Resistance A type of friction objects falling through the air experience. Newton’s 3rd Law For every action there is an equal and opposite reaction.
