Which statement is a hypothesis these students might be using in their
experiment?
A. If a toy car is rolled down ramps of different steepness, it will roll
fastest on the steepest ramp.
B. This experiment tests how the speed of a toy car changes with the
steepness of the ramp.
C. Will a toy car roll faster down a steeper ramp?
D. It's fun to see how fast the cars roll down the steepest ramps.

A statement of hypothesis to be used by the students in their experiment will be that if a toy car is rolled down ramps of different steepness, it will roll the fastest on the steepest ramp. Therefore, the option A holds true.

What is the significance of steepness?

Steepness refers to the angle at which any artificially created surface such as a ramp is kept, so that it does not hold any form of resistance to the gravitational force of the earth. More the steepness, greater is the gravitational pull of such force.

If an experiment is conducted where a toy car is rolled down ramps having different steepness, it can be inferred that the car will be at the fasted speed when the ramp is the steepest due to the maximum gravitational force.

Hence, the option A holds true regarding the steepness of ramp.
