Scalars and Vectors

Definition Scalar – a quantity that has a magnitude only, no direction. * YES, scalars can have units. ** What scalars have we learned about thus far? ___________ ____________ ___________ distance speed time I thought time could march backward?

Definition Vector – a quantity that has both magnitude AND a direction … oh yeh! * YES, vectors can have units. ** What vectors have we learned about thus far? ____________ ________________ ___________ position displacement velocity

Scalars vs. Vectors has magnitude & direction (example: 15 cm east) has a magnitude only (example: 6 ft) 1 2 A B Displacement is NEVER greater than distance traveled! Displacement: Distance:

Scalars vs. Vectors (continued) has magnitude & direction (example: 15 mi/h North) has a magnitude only (example: 30 km/h) If an object STARTS & STOPS at the same point, the velocity is ZERO! (since the displacement is zero) Velocity: Speed: km 7 km Total time for the trip from 1 to 2: 2 hr Speed = d/t = 15.5 km/h Velocity =  x/t = 12.5 km/h 25 km 16 o
