Circular Motion Flashcards
1
Q
Displacement=
A
Radius x Angle(radians)
2
Q
Omega (w)=
A
angular velocity (rad.s^-1)
3
Q
360 degrees=
A
2pi Radians
4
Q
a=
A
angular acceleration (rad.s^-2)
5
Q
tangential velocity v=
A
radius x angular velocity (rw)
6
Q
tangential acceleration a=
A
radius x angular acceleration (ra)
7
Q
Radial velocity=
A
0 (radius is always constant)
8
Q
radial acceleration=
A
v^2/r=rw^2 (towards the centre)
9
Q
F=ma becomes
A
F=m x v^2/r
