3 QuestionWhich ball can be thrown the farthest: a football , basketball , or tennis ball?
4 ResearchSpeed is a measure of an object’s change in position during a unit of time.Any push or pull is a force added to the ball.Any change in position is motion.Position is a certain place.A force is a push or a pull.Acceleration is any change in speed or the direction of an object’s motion.
5 HypothesisIf the ball type is changed , then the tennis ball will be thrown the farthest.
13 CONCLUSIONThe tennis ball was thrown the farthest which supported the hypothesis. Since the tennis ball had the least amount of mass, the force of the throw acted on the tennis ball more than on the other two ball types.In the future a similar investigation could be done. Instead of measuring distance, throwing speed with the different ball types could be tested.
