Circular Motion Flashcards
1
Q
Conditions for circular motion
A
Resultant force acts perpendicular to velocity
2
Q
define centripetal acceleration
A
the rate of change of tangential velocity
3
Q
define centripetal force
A
a force which acts on a body moving in a circular path and is directed towards the centre around which the body is moving
4
Q
define Radian
A
one radian is equal to to about 57.3 degrees
5
Q
how to convert from radians to degrees
A
radians x 180/π
6
Q
how to convert from degrees to radians
A
degrees x π/180
7
Q
velocity equation
A
(2πr)/T r is the radius of the circle and T is the Time period)
8
Q
Centripetal Acceleration equation
A
v^2/r (Velocity squared over radius)
