Practice Applying Circular Motion Formulas

5. Practice Applying Circular Motion Formulas

We can calculate velocity, acceleration, and force when traveling in a circle. In this lesson, we'll look at some sample problems using the formulas to calculate velocity, acceleration, and force of an object traveling in a circle.

What is Torque? - Definition, Equation & Calculation

6. What is Torque? - Definition, Equation & Calculation

You've probably heard of torque before, maybe while discussing cars. Now learn what it really is, and what it has to do with rotational equilibrium. Then, work through an example problem that combines the two.

Equilibrium: Translational & Rotational

7. Equilibrium: Translational & Rotational

Learn about the requirements for an object to be under translational or rotational equilibrium. Then work through a couple example problems that show how we can use translational and rotational equilibrium to find the forces acting on an object.

Rolling Motion & the Moment of Inertia

8. Rolling Motion & the Moment of Inertia

After watching this lesson, you should be able to figure out the moment of inertia of an object as it rolls down a ramp and compare it to a theoretical value. A short quiz will follow.

Rotational Inertia & Change of Speed

9. Rotational Inertia & Change of Speed

After watching this lesson, you will be able to explain what rotational inertia is, describe how it makes it harder to change the speed of rotation, and solve rotational inertia problems. A short quiz will follow.

Calculating Angular Momentum: Definition, Formula & Examples

10. Calculating Angular Momentum: Definition, Formula & Examples

Angular momentum is sometimes a tough concept to grasp, but with the right understanding and formula, it can be a snap. Let's explore its key concepts and give you some examples to help you understand.
