New cards

Uniform Circular Motion

an object moving at constant speed in a perfectly circular path

2
New cards

Tangential Velocity

the linear speed of any object moving along a circular path

3
New cards

Period (T [s])

  • the time it takes an object to complete one revolution at a given speed

  • delta t = T


4
New cards

Tangentinal Velocity Equation

  • delta S = C = 2 pi r

  • delta t = T

  • v = delta s/delta t

  • v = (2 pi r)/T


5
New cards

Centripetal (Center Seeking) Acceleration (a sub c)

  • the acceleration due to the velocity’s change in direction

  • delta v = (v² delta t)/r

  • a sub c = v²/r

  • F sub c = sum of all Forces = F1+F2+F3


6
New cards

Centripetal Force

  • F sub c = ma sub c
