A runner goes around a 1 mile track and ends up where he started what his is displacement?
Zero
200
What variable is on the Y-axis?
Velocity
300
The difference between displacement and distance?
Displacement is vector and is the change in position from initial and final point, regardless of path taken.
Distance is total path travelled and a scalar

A car travels a distance of 98 meters in 10 seconds. What is the cars speed?
9.8 m/s
300
A car slowing down to a red traffic light has a _________ acceleration.
Negative
300

In movies there are scenes where a horse and rider come to a fence; when the horse stops the rider flies over the horse's head. Explain why this happens.
Since you are riding the horse both the momentum of the horse and yourself are the same. When the horse comes to a stop and you are not secured then you will fly off at the speed/velocity the horse was moving when it stopped. This all happens because of the momentum of the horse.

Acceleration is the change of __________ over time.
Velocity
400
Two people travel from Bismarck to Fargo, one by car at a velocity of 95 km/hr, and one by plane at a velocity of 275 km/hr. Can their displacements by equal? Explain.
Yes, if their displacements are equal, as long as both people travel the same distance in the same direction.
