Conclusion: The result matches the prediction‚ as the height of the ramp increase‚ the speed of the toy car roll down on the ramp will increase because of the gravitational force pull the toy car down on the ramp‚ the higher height the toy car roll down on the ramp‚ the more gravitational forces involved‚ so the toy car will get a faster speed‚ but in the contrary‚ the lower height the toy car roll down on the ramp‚ there is less gravitational force‚ that’s mean the toy car will get a slower speed
