Conical Pendulum Demonstration and Problem

The video tutorial covers the concept of angular velocity using a conical pendulum demonstration. It begins with an introduction to angular velocity and unit conversion, followed by an explanation of the conical pendulum setup. The tutorial then delves into drawing free body diagrams and analyzing forces, breaking them into components. The process of solving equations to find angular velocity is detailed, including calculating the radius. The lesson concludes with verifying the results and a summary of the findings.

What is the first step in converting the given lengths from centimeters to meters?

• Divide by 10

• Multiply by 100

• Multiply by 1 meter over 100 centimeters

• Add 0.1 to each value

How does a conical pendulum differ from an ordinary pendulum?
