Learn how to calculate gravitational attraction between a point mass and a uniform rod using integration and Newton’s law of universal gravitation—essential for advanced physics students.

This video introduces basic concepts related to statistics, focusing on the idea of variables. Variables are defined as numbers or characteristics that can be counted or measured. The video gives examples such as age, length,...

You will use equations to solve perimeter of quadrilateral problems.

You will calculate missing side lengths in volume problems.

You will derive the area formula for parallelograms.

This video, entitled "Rotating Line Segments," explains how line segments can be rotated on a coordinate plane.

Area is the space inside a 2D shape. The rule for calculating the area of a rectangle is Length X Width.This formula doesn't work for compound shapes (shapes that are made up of two or more basic shapes).If we break down a compound...

The scale of the universe is bigger than you can imagine. It is also smaller than you can imagine. The smallest lenth theorized to be possible, the Planck length is about 4 X 10^-35 meters. Just imagine...

Is the universe infinite? Visualizing infinity. This is part 2 of the Planck length video. if the Sun was the size of a Basketball, Proxima Centauri our nearest neighbor would be 4500 hundred miles away. And...

Then Isaac Newton in 1687 showed that planets move due to the same forces we experience here on earth. If things could be explained with mathematics, to many people this called into question the need for a...
