Question

Quia - CH 7: Gravitational Potential E You have 00:26:42 left A marble is let go at position #1. It then rolls to all of the other positions in the diagram. It never stops in the diagram AND it coasts the entire way. - Position 3 and 4 are at the same height. Position 5 and 6 are also at the same height. 5 6 4 7 The marbles kinetic energy becomes the marbles friction The marbles gravitational potential energy becomes the marbles kinetic energy The marbles thermal energy becomes the marbles kinetic energy The marbles height decrease becomes the marbles speed increase 2 The marbles kinetic energy becomes the marbles potential energy The marbles kinetic energy becomes the marbles thermal energy

Explanation / Answer

when marble comes down then marble height and gravitaional potential becomes kinetic energy.

when marble goes theb=n reverse happens

kinetic energy is converted into thermal energy because of frcition but reverse cannot happen here.

so considering these facts

only options 1st and 5th are wrong

so tick the 2nd, 3rd, 4th, 6th
