Conical Pendulum Concepts and Forces

The video tutorial introduces the concept of a conical pendulum, defining its components and parameters. It poses key questions about tension, angle, and height, and analyzes the forces acting on the particle. The tutorial resolves these forces into vertical and horizontal components, discusses uniform circular motion, and solves equations to find the tension in the string.

What is the shape traced out by the motion of a conical pendulum?

• A cylinder

• A parabola

• A cone
