Some
simple formulas:
Formulas that will calculate: 

Velocity = 



Velocity = 

(These
formulas calculate the velocity if you know the distance an object falls.) 
Calculating
Centripetal Acceleration:
Centripetal Acceleration = 



Centripetal Acceleration = 

(Both
of these formulas calculate how fast an object accelerates toward the center
of a curved path.) 
Centripetal
Acceleration Example
Collisions:
mv
(object 1) = mv (object 1) + mv (object 2) 
(This
is a conservation of momentum formula. Use it when one object crashes into
another.)
