Topic awaiting preservation: Arc or Curve Functions

I'm starting to do simple game programming and it's been many moons since my high-school and college math classes. So anyone got any good resources for simple arc or curve functions? Nothing 3-d Just simple 2-d arcs.

Much thanks

Cool.

Could you be more specific though? Like, are you trying to

- move an object around in a circle
- make an object look like it's affected by gravity
- make an object follow an arbitrary path defined by control points

Check the Math and Physics category of ressources @ GameDev.net.

You should be able to find what you want, either it is something like projectile curves ( initial velocity, gravity, wind ), gravitational systems ( with attractive and repuslive objects ), spring systems ( single springs, sprint networks ), bezier/spline/nurb/catmull-rom curves ...

Right now it's to look like something is affected by gravity. The character needs to "hop" down a step.

Ok, so, check the Gravity FAQ listed in the link I gave above.

Seeing as gravity came up, how would this work with celestial bodies. Say a satalite orbitting earth? Given an intitial velocity and two masses such as the 5000kg satalite and the 5.9 x 10^24 kg earth? Do you know of a tutorial on that?
