Projectiles
|
vf= vi + at
vf^2=vi^2+2ad d=vit+½at^2 |
|
|
Sum of forces
|
F(Total) = F+F+F... = ma
|
|
|
Force of friction
|
Ffriction = μmg
Ffriction </= μFnormal |
|
|
Torque
|
torque = rFsinθ
|
|
|

G=6.67e-11
|
|
|
Force (centripetal)
|
F(c)=[mv^2]/r
This is not on the equation sheet, but it's FUCKING IMPORTANT so REMEMBER IT ANYWAY. |
