Chapter 6: Circular Motion Flashcards
1
Q
What is angular displacement?
A
The angle of rotation of a body about an axis in a specific direction from a reference point
2
Q
What is angular velocity?
A
The rate of change of angular displacement of a body with respect to time, swept out by the radius
3
Q
What is the relationship between linear velocity v and angular velocity ω?
A
v = rω
4
Q
State the formula for centripetal acceleration
A
a = v²/r
= rω²
5
Q
State the formula for centripetal force
A
F = ma
= (mv²) / r
= mrω²
6
Q
linear velocity
A
It is the rate of change of linear displacement
7
Q
1 radian/The radian
A
The angular displacement subtended if the arc length is equal to the radius
8
Q
Linear acceleration
A
The rate of change of linear velocity wrt time
