In order for an object to move at constant speed in a circle, an outside force must constantly turn the object toward the center of circular path.

A. Equations & Vectors
1. Centripetal Acceleration (ac) - acceleration toward center of curvature
| a)Equation: | ac = | V2 | |
| r |
b) (V) Instantaneous Velocity - tangent to circle, in the direction of the motion
c) Centripetal Force (Fc) - force directed toward the center of the circle
Ex) A car moving in a circular path with a radius of 2.0 m has a velocity of 8.0 m/s. What is the centripetal acceleration of this car?
Ex) A car moving in a circular path with a radius of 2.0 m has a velocity of 8.0 m/s. What is the centripetal acceleration of this car?
| a)Equation: | ac= | V2 | |
| r |
| ac = | (8.0 m/s)2 |
| 2.0 m |
a = 32. m/s2
