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.

Woah that’s a lot to read xd i’ll try though. i’ll get back t you if. i know the andwer

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
