Your teacher has asked you to perform an experiment to see if the shape of objects, alone, affects the motion of objects. which of the following would be the best experiment to perform? a. apply the same amount of force to balls of different masses. b. apply the same amount of force to a ball, cylinder, cube, and pyramid, each of a different mass. c. apply the same amount of force to a ball, cylinder, cube, and pyramid, each of the same mass. d. apply different amounts of force to the same ball.

The correct answer to the question: Which of the following would be the best experiment to perform, would indeed be, C: Apply the same amount of force to a ball, cylinder, cube, and pyramid, each of the same mass.

Explanation:

The reason for this being the answer comes from the request of the teacher. He wants to know if the shape of an object, and only that variable, will affect the object´s motion. As such, there are several things to keep in mind. One, that the objects selected for the trial, need to be different in shape; otherwise you would not be meeting the desired purpose of the test. Second, they must all be equal in mass, otherwise there would still be a new variable to think about for the test that has a very specific purpose, and what you want to do is minimize the variables. Third thing is, that the force used on the object, must be the same; otherwise another new variable would emerge. The one option that meets the requirements to answer the request from the teacher is, C.
