What is wrong with this picture?

What would a vector arrow look like for someone traveling 35 mph?

Review Is it possible to have a distance of 300 km, but a displacement of 0 km?

Why do we use the word speedometer instead of velocimeter?

Velocity Definition- Speed in a specific direction Speed is scalar, velocity is vector Example- Speed- 35 mph Velocity- 35 mph, West

2 types of velocity 1) Constant What would you have to have to have a constant velocity? Constant Speed and Constant Direction Would that be a straight line or a curved path?

2 types of velocity 2) Changing What would you have to have to have a changing velocity? Either the speed and/or direction must change

Name the 3 parts on a car that control velocity

Review 1) What is the difference between speed and velocity? a) none, they are the same b) speed is 2x faster than velocity c) speed has a direction d) velocity has a direction

Explain what is happening in this picture using the words speed and velocity

Review Change the following speeds to velocities a) 22.7 m/s b) 45 mph c) 67 km/h
