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?
A. Kinetic and potential energy are decreasing.
B. Kinetic and potential energy are increasing.
B. Potential energy is increasing, and kinetic energy is decreasing.
C. Kinetic energy is increasing, and potential energy is decreasing.
BTW I already did the Quick Check I just want to help yall out.:) the answers to the quick check are
D. Kinetic energy is increasing, and potential energy is decreasing.
A. at the top of the ramp before dropping in
C. The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point.
D. 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.
Hope this helps yall:)
Can I just say that this was oh so very kind of Carson to post this not even to cheat, but to help others with the test. It's really nice of you to post this for those who needed help with it and not just beg for answers for yourself. I took this test already today, but I can agree that Carson's answers are all correct. So, thanks a lot Carson!
The questions have changed a little
1. Kinetic energy is increasing, and potential energy is decreasing.
2. at the top of the ramp before they begin moving down into the ramp
3. The potential energy is increasing at point C because the bicyclist is increasing in elevation at that point.
4. half way down
number 4 : is half way down
THANKS CARSON
Guys please what is the answer!! to this quickchek I'm overdue so many lessons I just need this πππππππ°π₯π₯π₯
people who say carson is wrong, you can eat ur own words because i got 100 on the quick check, yall just read the answer wrong
potential energy = mg h decreases as h decreases
kinetic energy is increasing as speed increases (1/2) m v^2
