Mind map: Circular motion
Map content
Circular Motion
Angle
- Radians
- Arc length/ radius
- Scalar quantity
Velocity
- Angular velocity (ω)
- Rate of change of angle
- Vector quantity
- Radians per second
- Linear velocity (v)
- Speed of the particle in a direction perpendicular to the radius at that point
- Vector quantity
- Metres per second
- v = rω
- v = linear velocity
- r = radius
- ω = angular velocity
- Angular velocity (ω)
Periodic time (T)
- Time taken for one complete revolution
- T = 2π/ω
- T = 2πr/v
Centripetal acceleration
- Directed towards the centre of the circle
- Vector quantity
- Metres per second squared
- a = ω²r
- a = v²/r
Force
- Centripetal force
- Force required to maintain uniform circular motion
- Directed towards the centre
- Newton
- F = mω²r
- F = mv²/r
- Centrifugal force
- Opposing force
- Centripetal force
Circular satellite orbits
- Kepler's third law
- T² = (4π²R³)/GM
- Kepler's third law
Information
- Description
- This mind map provides an introduction to circular motion. Topics covered include angular & linear velocity, periodic time, centripetal acceleration, centripetal & centrifugal forces, and Kepler's third law. It is aimed at a leaving certificate student, or someone who has an interest in learning more about circular motion.
