Understanding the Center of Mass & Center of Gravity

1. Understanding the Center of Mass & Center of Gravity

The center of mass and the center of gravity may not always be equal, and this can have important implications. Learn how to determine the center of mass vs. the center of gravity, and review examples demonstrating that an object's center of mass and its center of gravity are not the same.

Rotational Kinematics: Definition & Equations

2. Rotational Kinematics: Definition & Equations

The study of kinematics concentrates on the motion of an object without referencing the force causing it. Learn more about the definition of kinematics and how to use the equations of rotational variables to calculate rotational kinematics.

The Relationship Between Angular Momentum & Torque

3. The Relationship Between Angular Momentum & Torque

Angular momentum and torque are both interrelated in physics, describing the forces of objects in motion and rotation. Identify the relationship mathematically and practically through examples.

The Principle of Moments: Definition & Calculations

4. The Principle of Moments: Definition & Calculations

When an object is free to rotate about a fixed axis, a force applied can cause the object to rotate. This lesson deals with the principle of moments, which is the turning effect on an object provided by a force.

The Parallel-Axis Theorem & the Moment of Inertia

5. The Parallel-Axis Theorem & the Moment of Inertia

The parallel-axis theorem is used to figure out an object's moment of inertia when it isn't going around a center of mass axis. Explore this theorem and how to find the moment of inertia using a provided equation and a detailed example calculation.

Torque: Concept, Equation & Example

6. Torque: Concept, Equation & Example

Torque refers to the rotational force acting on an object when applied offline from its center of mass. Explore the definition and concept of torque, and learn to apply the torque equation through example calculations.

Rolling Motion & the Moment of Inertia

7. Rolling Motion & the Moment of Inertia

The moment of inertia is a representation of the distribution of a rotating object and the amount of mass it contains. Learn about rolling motion and the moment of inertia, measuring the moment of inertia, and the theoretical value.

Angular Momentum vs. Linear Momentum

8. Angular Momentum vs. Linear Momentum

Angular momentum is used to describe a rotating motion while linear momentum is concerned with translating motion. Learn more about the definitions of angular and linear momentum, and also the two different equations used to calculate angular momentum.
