Motion • The process of changing position.
Distance • The total length of your path.
Displacement • The distance between your starting position and your final position. • In a straight line.
Displacement = 9 m B 9 m A 5 m 4 m 6 m Distance = 15 m
Speed • The rate at which an object moves.
Average Speed • The distance an object moves divided by the time it took to move that distance.
Instantaneous Speed • An object’s speed at one instant.
Constant Speed • Speed that does not change.
Velocity • The speed AND DIRECTION of an object’s motion.
Acceleration • When an object’s speed or velocity changes, the object is accelerating.
Positive Acceleration • When an object is speeding up.
Negative Acceleration • When an object is slowing down.
