Mr. Andersen explains the basics of balancing chemical equations. A visual guide shows you how to change coefficients to balance the atoms in reactants and products.

New ReviewIn this math video, viewers are guided step by step through solving a problem where the first four terms of a geometric sequence are given and the goal is to write an equation for the nth term. The exemplar solution begins by introducing...

Discover the fascinating interplay between buoyant force, Newton’s third law, and free body diagrams in this hands-on physics demonstration. We explore how forces interact when a steel or oak sphere displaces water in a beaker on a...

This is a review of all of the dimensions used in AP Physics C - Electricity and Magnetism.

A formal proof of the parallel axis theorem. It's really useful for finding moments of inertia of composite objects and also objects which aren't rotating around the center of mass.

Upon viewing the Investigating Chemical Reactions video series, students will be able to do the following: Define a chemical reaction as a process in which substances undergo changes to produce new materials with different properties....

What is the velocity a block must have such that it compresses the spring by 10cm? This will test your knowledge of Newtons laws and motion analysis: eg, dv/dt = a

This is a lecture video on the turns ratio equation for transformers. The video explains how the potential difference across the primary and secondary coil of a transformer depends on the number of turns of wire in each of the coils. The...

What is the equation of motion of a particle that has a drag force acting on it? It's important to note that we've assumed that the drag force is proportional to the velocity at all times. In reality, other factors are involved too...

Here, I show you how to write the formula for an ionic compound given the cation and anion. [5 examples]

👉 Learn how to evaluate the integral of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiation. Integral of a function can be evaluated as indefinite integral or as a definite...

Mathcad is a tool to arrange, calculate, and visualize engineering calculations. A Mathcad sheet has values, equations, plots, and functions that are written and displayed in a manner that is similar to how they are written in a textbook...

The video explains the differences between step up and step down transformers. It starts with an introduction to the purpose of transformers and the primary and secondary coils. The video then goes on to describe the two types of...

👉 Learn how to condense logarithmic expressions. A logarithmic expression is an expression having logarithms in it. To condense logarithmic expressions means to use the logarithm laws to reduce logarithm expressions from the expanded...

👉 Learn how to find the slope between two points. The slope of a line is the steepness of the line. The horizontal line has a zero slope while the vertical line has an undefined slope. To determine the slope of a line passing through two...

👉 Learn how to write the rule of a sequence given a sequence of numbers. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. To write the explicit formula of...

👉 Learn about sequences. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. There are many types of sequence, among which are: arithmetic and geometric...

Ix is the second moment of area about the x axis. Choosing the value of dA is the important part for this problem. In this example where we're dealing with a section of a circle, it's easier to use cylindrical coordinates dA = r dr...

👉 Learn how to find the midpoint between two points. The midpoint between two points is the point halfway the line joining two given points in the coordinate plane. To find the midpoint between two points we add the x-coordinates of the...
