Circular Motion Round and Round
Circular Motion Velocity is always changing because when traveling in a circle the direction is always changing!
Circular Motion It is often best to describe circular motion in the time it takes to complete one circle or T
Circular Motion It we know the radius of the circle r we can calculate centripetal velocity using the circumference = 2πr
Circular Motion 2πr v = T
Circular Motion When objects are moving in a circle the acceleration is towards the center!
Circular Motion 2 v a c = r
Circular Motion Now we substitute our velocity equation for v 2 v a c = r
Circular Motion Now if we know time we can find centripetalaccelerationa 2 4πr a c c = 2 T
Circular Motion Solve this equation for velocity 2 v a c = r
Circular Motion Now we can find our centripetal velocity v = a r c
