Science Buddies: "Ask an Expert"

Hi Science Buddies!
I am currently working on a project about the theory of forces and how it affects the speed of the object. I have an example, which is skateboarding that goes down a ramp and increases within speed, the steeper the ramp is. However, I am struggling understanding what affects of the forces on the skateboard. And am in dire need for your help....

Hi,
I think the following does a pretty good job of explaining the gravitation forces that will be impacting the skateboard on the ramp: https://www.khanacademy.org/science/ap- ... components

Please take a look and post again if you have any questions!
