Conical Pendulum Concepts and Forces

The video tutorial explores the concept of circular motion, focusing on a particle moving in a circle on a flat surface. It introduces the conical pendulum, where the string is lifted, forming a cone shape. The tutorial delves into the forces at play, including tension and weight, and explains how these forces balance to maintain uniform circular motion. Key equations are derived to understand the relationship between tension, angular velocity, radius, and mass. The tutorial emphasizes the importance of resolving forces and understanding the variables affecting tension in the string.

What is the shape traced out by a conical pendulum?

• A triangle

• A square
