Question

An investigation is performed to determine how the angle of a ramp affects the speed of a ball as it rolls down the ramp. In addition to using the same ball and the same ramp, which of these should also remain constant? A. Releasing the ball from the same position in each trial. B. Keeping the ramp at the same height for all trials. C. Keeping the ramp facing the same direction for all trials. D. Measuring the length of the ramp before each trial.

Answer 1

A ramp can affect the speed of an object rolling down the ramp because the pull of gravity acts on the object inclined at a steeper angle which makes the object to accelerate and move faster.

From the question, we were told an inverstigation was performed to detrmine how the angle of the ramp affects the speed of a ball as it rolls down the ramp.

Using the same ball and the same ramp the
