1. Torque in Physics: Equation, Examples & Problems
After watching this video, you will be able to explain what torque is and use an equation to calculate torque in simple situations. A short quiz will follow.
2. Torque: Concept, Equation & Example
After watching this lesson, you will be able to explain what torque is conceptually and mathematically and use both the equation and Newton's First Law for rotation to solve problems involving torque. A short quiz will follow.
3. Understanding the Center of Mass & Center of Gravity
After watching this video, you will be able to explain the difference between center of mass and center of gravity and give examples of situations where they would be different. A short quiz will follow.
4. What is Center of Gravity? - Definition, Equation & Examples
Understand the meaning of the center of gravity (CG) and its effect on the stability of an object. Learn how to calculate the CG of different systems of objects with a series of examples.
5. Stability & Center of Gravity
Discover what stability means and why center of gravity is so important to understanding it. Then learn about the different states of stability and how to tell the difference between them.
