Term
 Newton's First Law of Motion
Definition
 InertiaEvery object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Term
 Newton's Second Law of Motion
Definition
 the applied force = an object's mass x its accelerationF=MA
Term
 Newton's Third Law of Motion
Definition
 For every action there is an equal and opposite reaction.
Term
 Scalars (definition and example)
Definition
 Quantities that are fully expressed by a magnitude (numerical value) alone.For example: distance, speed
Term
 Vectors (definition and example)
Definition
 Quantities that are fully expressed by a magnitude (numerical value) and a direction.In 1D we use positive and negative, and in 2D we use angles.For example: displacement, velocity
Term
 Conversion from m/s to km/hr
Definition
 Multiply by 3.6
Term
 Conversion from km/hr to m/s
Definition
 Divide by 3.6
Term
 Acceleration of gravity
Definition
 -9.8(m/s)/s if up is +ve
Term
