1) what is the potential energy at the end of the loop? 2)what is the kinetic energy at the end of the loop(based upon photogate time?

release the car and record the time from the photogate at the bottom of the hill and answer the top questions:
i attached an image that shows the recorded time this is a class work but i’m trying to get better at it

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
