What are oscillations equations without gravitation equations?

Gravitation:

T12/R13=T22/R23

G= 6.67x10-11

g=Gm/r2

Fg= -Gm1m2/r2

Potential Energy= -Gm1m2/r

Vorbit= [Gm1/R]1/2

Vescape= [2Gm1/R]1/2

T=(2(pi)R)/v

Total energy for a circular orbit= (-Gm1m2)/(2R)

Total energy for elliptical orbit= (-Gm1m2)/(2a) ; a= major axis radius

Velocity/Radius relationship for elliptical orbits: vprp=vara

Overall, there aren't too many equations to remember for this topic. But, all of the equations are very similar. So, memorize!
