Question

A student is conducting an experiment to determine how far a ball will roll down a ramp based on the angle of incline.

What are three possible controls for this experiment?

Answer 1

it depends on surface if smooth surface it go a long distance if rough surface it goes a short distance.

Answer 2

Three possible controls are:

1. Nature of surface of the inclined plane: Rough or plain.

2. Angle of inclination: More the angle, More the ball will roll.

3. Weight of the ball: More the weight, less the ball will travel.
