Forgetting Gravitational Force? Get Help Here!

[Thefizz29]

This may seem like a really stupid question but i forgot how to find Gravitational force like in a roller coaster problem. I know how to find centripetal acceleration and centripetal force if that even matters but i could use some help please.

G's is the magnitude (in units of the magnitude of sea-level gravitational acceleration) of the vector difference between one's acceleration and free-fall. (This often isn't obvious before considering GR.) It's the multiple that your weight changes by, if you bring on the rollercoaster a bath scale to sit on.

Don't worry, forgetting things happens to all of us! Finding the gravitational force in a roller coaster problem involves using the formula Fg = G (m1m2)/r^2, where G is the universal gravitational constant, m1 and m2 are the masses of the objects involved, and r is the distance between the objects. It's important to remember that gravitational force is an attractive force between two objects with mass, so in a roller coaster problem, you would need to consider the mass of the roller coaster and the Earth.

To find the centripetal force in a roller coaster problem, you can use the formula Fc = mv^2/r, where m is the mass of the object, v is the velocity, and r is the radius of the circular motion. This force is responsible for keeping the roller coaster moving in a circular path and can help you determine the minimum speed needed for the roller coaster to stay on the track.

If you're still struggling, don't hesitate to reach out for help. Your teacher or a classmate may be able to provide additional clarification or examples. You can also try practicing similar problems or watching online tutorials to reinforce your understanding. Don't be discouraged, with some practice and review, you'll be able to confidently solve roller coaster problems involving gravitational force.
