Calculating Velocity
Calculating Velocity
g = the acceleration due to gravity: 9.8 m/s/s
d = drop in height. Measured in meters.
vi = Starting velocity. Initial velocity.
(These formulas calculate the velocity if you know the distance an object falls.)
Calculating Centripetal Acceleration
Calculating Centripetal Acceleration
g = the acceleration due to gravity: 9.8 m/s/s
d = drop in height. Measured in meters.
r = radius of curved path. Measured in meters.
(Both of these formulas calculate how fast an object accelerates toward the center of a curved path.)
Collisions:
Collisions:
mv (object 1) = mv (object 1) + mv (object 2)
mv (object 1) = mv (object 1) + mv (object 2)
(This is a conservation of momentum formula. Use it when one object crashes into another.)
