Chapter 17 - Motion In A Circle Flashcards
1
Q
What is uniform circular motion ?
A
An object which is rotating at a steady speed
2
Q
What is angular speed ?
A
Angular speed is defined as the angular displacement per second
3
Q
What is angular displacement ?
A
Angular displacement in the time t is 2Pit/T
Where T is the time for one rotation
4
Q
What is centripetal acceleration ?
A
It is the acceleration of the object towards the centre of the circle.
5
Q
What is centripetal force ?
A
It is the resultant force on an object that moves along a circular path.
6
Q
What is the equation for force of friction ?
A
Force of friction f = (mv^2)/r
7
Q
What is the limiting force of friction ?
A
F0= (mvo^2)/r
Where fo is proportional to the vehicles weight
F0=(coefficient of frictionmassg
