## Study Notes

### Uniform Circular Motion

• The expression for centripetal or radial acceleration in uniform circular motion is a = v²/r, where a is the acceleration, v is the velocity, and r is the radius of the circular path.
• The acceleration in uniform circular motion depends on velocity and radius of the circular path.
• The expression for the magnitude of centripetal acceleration in uniform circular motion is a = v²/r.
• The centripetal acceleration is directed towards the center of the circular path, meaning it is always directed radially inward.
