Speed and velocity (Right) W. is the formula for speed? What if I need to find out distance or time? 3) How is velocity different from speed? 4) W. is the diff. btw scalar & vector quantity? Speed = distance/ time. Units can vary. 2) Distance = speed * time Time = distance/speed 3) Velocity is speed and direction. 4) A scalar quantity has a number and unit. A vector has a magnitude and direction.

Speed = distance/ time Distance = 5m, time = 5s. Find Speed Distance = 40km, time = 2 hours. Find S Speed = 3m/s, time = 1s. Find Distance.

Velocity= distance/ time (+direction) Going North, Distance = 20m, time = 5s. Find Velocity Going West, Distance = 40km, time = 4 hours. Find V

Exit slip The formula for speed = time/distance True b. false 2. Velocity is distance and direction a. True b. false 3. Distance = 10m time = 10s Calculate speed 4. Distance = 20m time = 4 s Calculate speed 5. Time = 10s speed = 30m/s calculate distance *** MUST USE CORRECT UNITS
