Physics Middle School

Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.


The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment: (second image)


The students finish conducting their tests and conclude that using a taller ramp and a larger ball will make the ball roll further. Is their conclusion based on a reliable experiment?

A.Yes, because they used the same color balls.


B.No. They did not do an additional test to compare the results using the short ramp.


C.No. The small ball should have been pushed with more force.


D.Yes, because they changed the height of the ramp.

Answers

Answer 1
I would say it’s “B” for the reason that the student did not experiment with a short ramp and large ball as well as a large ramp and a short ball. They have to do those experiments as well before drawing their conclusion.
Answer 2

Answer the larger ball will reach late.

Explanation:the smaller ball will reach before because it's density is low because of its small size and the small ball will reach before because it's lighter
