Explain the effect of increasing the height of the roller coaster on its speed. --------------------------------------------------------------------- 2. One student thinks that the marble has its maximum gravitational potential energy at the highest point on the roller coaster; the other thinks that the marble has the maximum gravitational potential energy at the lowest point on the roller coaster. Discuss the two points of view and give your opinion on which you agree with. en-us 2018-03-07 03:05:38 UTC 2018-03-07 04:55:23 UTC hello@padlet.com https://padlet.com/gayathri_arjunan/ghksmiik587l/wish/238995389
1) when the roller coaster speed increase the height will decrease when the speed decrease the height increase .

So if the the hight increased the speed will do as well, in addition to that if the hight decrease the speed will increase.

2. I agree with the first opinion because its a rule that the highest point the roller coaster
is the gravitational potential energy , for the second opinion the kinetic energy will be higher because it will still move .]]> 2018-03-07 04:27:21 UTC https://padlet.com/gayathri_arjunan/ghksmiik587l/wish/238996130 https://padlet.com/gayathri_arjunan/ghksmiik587l/wish/238996202 1- When the height of the roller increases the speed it also increases, if the speed is increased, the kinetic energy must also increase . This means that the kinetic energy for the roller coaster system is greatest at the bottom of the largest downhill slope on the track. 

2- in my opinion the first student is correct because of that what we learned from the equation, what it's mean that the maximum GPE is at the highest point, but the second student is not correct because she is saying the opposite of the rule in the equation, because according to the formula, gravitational potential energy is equal to mgh ]]> 2018-03-07 04:27:59 UTC https://padlet.com/gayathri_arjunan/ghksmiik587l/wish/238996202 https://padlet.com/gayathri_arjunan/ghksmiik587l/wish/238998044 2018-03-07 04:43:46 UTC https://padlet.com/gayathri_arjunan/ghksmiik587l/wish/238998044 https://padlet.com/gayathri_arjunan/ghksmiik587l/wish/238998046 1) the firs opinion illustrates the highest point of the roller coster makes the marbles Gravitational Potential Energy with is ( mass x gravity x hight ) will reach the maximum 

2) the other opinion says the opposite, "the Gravitational Potential Energy is on its maximum when its on the lowest point
