Force & Motion Ch.1 Review

Students have short and tall ramps, and identical toy cars with which to 

perform an investigation.

Which of the following is a testable question they could answer in an 

investigation using these materials?

• Which material should engineers use for high traffic roads?

• Does the mass of the toy car affect the speed at which it rolls down the ramp?

• Does the height of the ramp effect the distance the toy car will travel?

• Will the length of the toy car affect the distance it will  travel?
