Question

Sample Response: If the speed of an object increases, then its kinetic energy will increase proportionally because speed and kinetic energy have a linear relationship when graphed.

What did you include in your hypothesis? Check all that apply.

The speed of the object can be changed.
The kinetic energy will be measured.
Analysis can include using a graph.

Answer 1

All three.

- The hypothesis starts with “If the speed of an object increases,” which implies the speed can be changed.
- It predicts a change in kinetic energy, so kinetic energy will be measured.
- It mentions a linear relationship “when graphed,” so analysis can include using a graph.
