Acceleration directed toward the centre of circular motion.

(Δv)– Final velocity minus initial velocity.

The event that occurs when velocity passes through zero and changes sign.

motion in which an object's speed increases or decreases.

The rate at which the separation between approaching objects decreases.

Two angles whose sum is 90°.

Part of a vector acting along a selected axis.

Velocity changing by the same amount each second.

motion where speed does not change.

Motion with unchanged velocity.
