Milton is conducting an experiment to see how far a marble will
roll when he releases it at the top of an inclined plane. Why
does the marble speed up as it travels down the inclined
plane?
a
The marble has a greater mass as it travels faster.
The force of friction is reduced because the
marbles surface is smooth.
The force of gravity pulls the marble down the
inclined plane.
The marble has less magnetic attraction to the
inclined plane as it travels.
