Question

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

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

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

Answer 1

All three apply.

- The mass of the object can be changed — the hypothesis begins “If the mass of an object increases…”.
- The kinetic energy will be measured — it predicts a change in kinetic energy (the dependent variable).
- Analysis can include using a graph — it explicitly refers to the relationship “when graphed” and calls it linear.
