Circular Motion
Cards in this deck (11)
- 1What does uniform circular motion mean?An object rotation at a steady rate
- 2What is the equation used for finding the circumference of a circle?2πr / πd
- 3How do you calculate the frequency of a rotation?f = 1/T (T being time for 1 rotation)
- 4How do you calculate the speed (v) of a point on the perimeter?v = 2πr/T
circumference/time for one rotation - 5How do you calculate angular speed?w = angular displacement/time taken
- 6How do you calculate centripetal acceleration?a = v2/r
- 7What is centripetal acceleration?When an object is moving in a circle at a constant speed (the velocity of the objects is continuously changing).
- 8Why does centripetal acceleration happen?Due to the velocity constantly changing, the object is accelerating. The objects speed however doesn't change.
- 9What is centripetal force?For an object to move around on a circular path, it must be acted on by a resultant force that changes the direction of its motion.
- 10What is the resultant force when involved with centripetal force?The resultant force is the centripetal force because it acts in the same direction as centripetal acceleration (towards the centre of the circle)
