Nonuniform Circular Motion - Force of Tension in a Rope (9:50)
|
Determining the force of tension in a string as a function of angular position for a ball moving in a vertical circle. A ball of mass m on the end of a string of length L moves in a vertical circle with a non-constant angular speed ω. The string forms an angle θ with the vertical. Determine the tension in the rope in terms of m, L, ω, θ, and known constants. This is an AP Physics C: Mechanics topic.
