Circular Motion Flashcards
1
Q
Angular displacement formula
A
Change in s/ r
2
Q
Radian definition
A
Angle subtended at the center of a circle by an arc equal in length to the radius of the circle
3
Q
Angular speed definition
A
Rate of change in angular displacement with respect to time
4
Q
Angular velocity formula
A
W=v/r
5
Q
Centripetal acceleration definition
A
Acceleration of an object towards the center of a circle when an object is in motion around a circle at constant speed
6
Q
Centripetal acceleration formula
A
A=v^2/r linear speed/ radius
A=rw^2
A=vw
7
Q
Centripetal force formula
A
F=mv^2/r
f=mrw^2
F=mvw
8
Q
Angular displacement definition
A
Change in angle, in radians of a body as it rotates
9
Q
Angular speed formula
A
W= change in angular displacement/ change in time
W= 2pi/ T
W= 2pif
