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.
Acceleration is the change of __________ over time.
Velocity
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.
