Hi. I have a question relating to science, but I need the answer to write a program. So, let's see if you have an answer.
Say we are in a place with very little friction. Now, we take a hill and put a car at the top. We also put a car on a crain, holding it up at the same height as the hilltop.
Without friction, all objects on earth fall at 9.8m/s(squared). Saying we let the car on the hill roll (remember, very little friction), what would be the change in velocity. It would not fall at the same rate. Is there a formula for this?
I am making a roller coaster sim.
