Mr. Andersen describes the relationship between voltage, current and resistance in an electric circuit. Ohm's Law is introduced through a circuit simulation.

Mr. Andersen explains the concept of momentum. He also shows you how to solve simple momentum problems. He finally shows you how momentum is both conserved and relative.

Let's go and explore one of the fastest ways to graph a linear equation. Often we assume slope intercept is the easiest and fastest method, but that is not always the case.

In this video, I demonstrate simple methods for solving linear equations containing fractions, specifically focusing on two step equations. We explore how fractions can show up in our equations and how to use problem-solving strategies...

In this video a student asked me to graph a line in standard form. I will show you two different ways to graph.

In this math video, we’ll explore how to determine if a table represents an exponential function using a real-world bacteria growth scenario.

We start with a culture that begins with 1,000 bacteria, and each hour, the...

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 provides a creative and engaging way to help students understand and remember how to work with exponents. By using the analogy of Big Brother representing the base and Little Brother representing the power, the video...

A video entitled "Complement" which shows what a compliment is and how it is useful.

You will use unit rates to solve real-world application problems.

You will calculate missing side lengths in volume problems.

We've covered the basics regarding second-order differential equations and their solutions, for both linear homogenous and nonhomogenous differential equations. Now let's look at some special second-order types, such as Cauchy-Euler, and...

We just looked at some simple ways to solve systems of differential equations, via modeling and elimination. But there are other methods, some of which involve matrices. This will require that we remember some concepts from linear...

Explore this classic gravitation problem where three masses form an equilateral triangle and a fourth mass is placed at the center. Learn how to calculate the mass required for gravitational force balance and why doubling the central...

Pupil outcome: I can identify the addends and the sum in column addition. Key learning points: - In column addition, one addend is written below the other. - The equals sign shows it is an equation. - The sum appears within the equals sign.

Pupil outcome: I can recognise that there are many different types of equations of which linear is one type. Key learning points: - An equation is a statement that two expressions are equal, indicated by =. - Linear expressions can be...

Pupil outcome: I can use the general form for a directly proportional relationship to find k. Key learning points: - Direct proportion equations are of the form y = kx - k is the constant of proportionality and it is also the gradient of...

Pupil outcome: I can identify, from their equations or graphs, whether two lines are parallel. Key learning points: - Two lines are parallel if they are equidistant and never touch. - For linear graphs, the rate of change is constant. -...

This video provides a detailed solution to a Grade 11 physics problem involving the work done by a spring force on a box on an inclined plane. It explains how to calculate the work done by the spring as the box moves and the concept of...
