Question

Ms. Simpson's science students were observing a Newton's cradle. They noticed that when the ball was raised and released on the left side, it hit the stationary balls, and its kinetic energy was transferred all the way to the last ball on the right, causing it to be propelled up. This action continued for a while, but as time went on, the balls did not go as high and eventually stopped. Why did the balls stop moving? *
A-The three middle balls blocked the energy from getting to the outside balls, so they could not rise as much. B-The combined mass of the balls could not be overcome by the force of one moving ball. C-Due to air resistance and friction between the string and the frame, some of the energy was transferred to the surroundings. D-Due to the force of gravity pulling the balls down, energy was continually lost to the surrounding environment.

Answer 1

Ok, so gravity pulls things down right

Answer 2

yes

Answer 3

and gravity is transformed from one to other things or energys and cannot be lost or made

Answer 4

so gravity pulls down on everything

Answer 5

so its D?

Answer 6

Yes, that is what I believe I also looked it up to make sure and it says that gravity pulls them down and slows them.

Answer 7

So it is D

Answer 8

thanks once again(:

Answer 9

No problem
