Circular Motion Flashcards
1
Q
How to calculate for angular displacement?
A
=S/R
2
Q
What is one radian?
A
the angle subtended at the centre of a circle by an arc equal to the radius of the circle.
3
Q
Linear velocity formula?
A
V =rw
4
Q
Centripetal Acceleration Formula?
A
a= rw^2, v^2/r
5
Q
Centripetal force?
A
Resultant of all the forces that act on a system in a circular motion (not included in FBD)
6
Q
Formula for centripetal force?
A
F= mrw^2 = mv^2/r
7
Q
Reason for weightlessness?
A
Person and satellite has the same acceleration, hence normal reaction on person is zero.
