Uniform acceleration - ANSWER- constant acceleration


Uniform acceleration equation - ANSWER- final velocity^2-initial velocity^2 = 2 x

acceleration x distance


Distance-time graph - ANSWER- gradient = speed


Velocity-time graph - ANSWER- shows how velocity is related to time


Friction - ANSWER- A force that opposes motion between two surfaces that are in contact


Drag - ANSWER- resistance by friction from air or water moving over a surface


Terminal velocity - ANSWER- the constant velocity of a falling object when the force of air

resistance is equal in magnitude and opposite in direction to the force of gravity


Factors affecting terminal velocity - ANSWER- shape and area


A zero resultant force means - ANSWER- no acceleration


Newton's second law - ANSWER- F = ma


Inertia - ANSWER- The tendency of an object to resist a change in motion
