A student conducts an experiment to determine the speed of a toy car at the bottom of a ramp after it is released from different heights on the ramp. The student makes one measurement for each height.

What is one way that the student could improve the experiment?

Responses

use a different ramp for each height
use a different ramp for each height

use a different timer for height

perform multiple trials for each release height instead of just one
perform multiple trials for each release height instead of just one

perform one trial for each measurement but use a different car for each height

One way that the student could improve the experiment is to perform multiple trials for each release height instead of just one. This would help to account for any variations in the toy car's speed due to experimental uncertainty, providing more reliable and accurate data for determining the speed at each height. Multiple trials will also allow for better statistical analysis of the results.
