A person is riding a skateboard on a U-shaped ramp. At which point does the person have the greatest potential energy?(1 point)
in the middle of the ramp at the lowest point
in the middle of the ramp at the lowest point
on the upswing as the person is coming up the other side of the ramp
on the upswing as the person is coming up the other side of the ramp
on the downswing as the person is dropping into the ramp
on the downswing as the person is dropping into the ramp
at the top of the ramp before dropping in
by the way, the answer is:
"At the top of the ramp before dropping in"
If you're doing the Potential Energy of a System Quick Check here's the answers .1 The girl in the picture is at the highest point in swinging and starts to come down. Which statement best describes the changes in energy as she begins to
descend? Answer is Kinetic energy is increasing, and potential energy is decreasing. .2 A person is riding a skateboard on a U-shaped ramp. At which point does the person have the greatest potential energy? Answer is at the top of the ramp before dropping. .3 At which of the three points, if any, is the bicyclist's potential energy increasing? Answer is The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point. .4 How would potential and kinetic energy change when going down stairs one at a time versus two at a time? Answer is If you go down stairs two at a time, then your potential energy relative to the stair is greater. Your kinetic energy will be greater when you
land. If you think I wrote to much I had to because people usually can't find the answer.
1.) Kinetic energy is increasing, and potential energy is decreasing
2.) At the top of the ramp before dropping in
3.) The potential energy is increasing a point C because a bicyclist is increasing in elevation at that point
4.) if you go downstairs two at a time then your potential energy is relative to the stake is greater. Your kinetic energy will be greater when you land.
They don't double it, it's just that when you copy and paste a question for some reason (maybe because of the font), the answers get doubled. Not completely sure why tho.
Bruhstopit is correct
