Circular Motion Flashcards
Angle in radians
Arc length / radius
Angular Velocity
rate of change of angle with respect to time
Unit of angular velocity
rad per second
w (angular velocity)
theta over time
relationship of linear speed and angular velocity
v = rw
Centripetal force
resultant of all external forces acting on a particle executing circular motion towards the centre if the circle, maintaining that particle in circular motion
centripetal acceleration
if a body is moving in a circle the acceleration it has towards the centre go the circle
F =
Gm(1)m(2) all over d squared
v squared =
GM over R
Period of an orbit
time taken for a satellite to go once around the central body is called the period (T) of an orbit
T squared =
4pie(2)R(3) over GM
Centre of gravity
point within that object from which the force of gravity appears to act
