**acceleration**The rate of change of velocity; it measures how quickly an object speeds up or slows down.

**affine**As in “affine transformation,” indicates that the essential shape of the object being moved is preserved.

**amplitude**Measures the range of output values for the sine or cosine function.

**angle of incidence**The incoming angle of a moving object when it collides with a fixed object.

**angle of reflection**The outgoing angle of a moving object when it collides with a fixed object.

**angular displacement (θ)**A vector quantity that measures rotation. It is equal to the arc length divided by the radius of a rotating object.

**Angular Momentum**(L = Iω) where I=inertia (mr

^{2}) and ω=angular velocity.
