The conic pendulum is a system consisting of a mass hanging from a fixed point by a rope of length . It spins around the vertical with angle and with angular velocity . As the angular velocity increases, the angle from the vertical increases.[more]
The forces acting on the mass are the weight (red) and the tension (green), with resultant the centripetal force (magenta) equal to . The velocity vector is shown in yellow.
Finally, the relation between the angular velocity and the angle is .
For simplicity, the mass is taken as 1 kg and the radius equal to 1 m.[less]
