Question

Physical science B help ?

Answer 1

It's about the physics of a roller coaster (kinetic and potential energy that stuff)

Answer 2

Shoot.

Answer 3

Before you state your question do you understand the difference between KE and PE?

Answer 4

Kinetic is moving and potential isn't?

Answer 5

Your right. But formally know the definitions to help you in the future.
Kinetic energy : Energy of motion
Potential energy: The "potential" for an object to do work.

Answer 6

Well I have a formula GPE question I have many actually that's what I need help on

Answer 7

Go ahead! I'll try to help as much as I can :)

Answer 8

Aside from your coaster’s mass, what other measurements (numerical values) need to be known before you can use the formula in step #1 to calculate GPE? My coasters mass is 800 kg I said meters or height

Answer 9

\[G _{PE} = mgh \]

Mass= kg
Height = m
gravity = 9.8m/s^2

Answer 10

That's pretty much what you need to calculate GPE.

Answer 11

I think its gravity cause it said numerical value

Answer 12

Wait, the question is you want to calculate GPE right?

Answer 13

yeah

Answer 14

yea gravity is that numerical value. Its a constant 9.8m/s^2

Answer 15

do I multiply all of those values or?

Answer 16

yea do you have the height though?

Answer 17

GPE = m x g x h

Answer 18

80m

Answer 19

x = multiply

Answer 20

Yea, so its 80x9.8x800

Answer 21

is it normal to be a big number?

Answer 22

Yea! :)

Answer 23

Its very normal.

Answer 24

Okay I think I can do the rest now that I know what im doing :)

Answer 25

Good luck!
