Question

sample response: if the starting height of a sloped racetrack is increased, then the speed at which a toy car travels along the track will increase because the toy car will have a greater acceleration. what did you include in your hypothesis? check all that apply. ☐ the \if\ part of the hypothesis refers to changing the height of the racetrack. ☐ the \then\ part of the hypothesis refers to a measurable difference in speed. ☐ the \because\ portion of the hypothesis connects the ideas of speed and acceleration.

Explanation:

The hypothesis structure is analyzed. The "if" part is about changing racetrack height. The "then" part is about speed difference. The "because" part connects speed and acceleration.

Answer:

All three options should be checked.

• The "if" part of the hypothesis refers to changing the height of the racetrack.
• The "then" part of the hypothesis refers to a measurable difference in speed.
• The "because" portion of the hypothesis connects the ideas of speed and acceleration.
