In this shorts math video we will write & solve a real world system of linear equations. We will define our variables and use the information provided to write two linear equations in two variables. We will understand that the sum of...

In this shorts video we will learn how to write the equation of a line. We will begin by discovering that all the given answer choices are in slope-intercept form; y=mx+b. We will then review the information about the line that is...

In this math video we will learn how to interpret, use and write an equation. We will review how an equation represents a real world relationship where y represents miles and x represents hours. We will also review that the coefficient...

Electric potential is one of the most important ideas in electrostatics, and in this video, Mr. P from Flipping Physics clearly explains what electric potential is, how it differs from electric potential energy, and how to calculate it...

Learn how astrophysicists use the orbital motion of a visible star—its speed and period—to infer the mass of its invisible companion, often a black hole, in a binary system.
