DISTANCE

The actual path an object travels

The object may turn and curve.

slide8

DISPLACEMENT

Straight line path from start to finish, shortest distance.

Tells how far and gives a direction.

Measures the change in an object’s position.

To calculate how fast an object is moving we need to measure

Distance (D) in meters

Time (T) in seconds

slide31

Direction in which you are moving.

Centripetal acceleration

Occurs during circular motion.

slide32

Time (T) seconds, for which the object travels.

Initial Velocity (Vi), or starting velocity of an object

Final Velocity (Vf), or the ending velocity of the object.

slide37

∆ V = Vf – Vi

CHANGE = FINAL – INITIAL
