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.
