I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips. I believe everyone can learn math...

A 0.453 kg toy car moving at 1.15 m/s is going up a semi-circular hill with a radius of 0.89 m. When the hill makes an angle of 32° with the horizontal, what is the magnitude of the force normal on the car?

In this video, students learn about opposite numbers on a number line and how they can be combined to make zero. Using real-life examples involving distance and direction, the video demonstrates how positive and negative directions can...

Solving a basic projectile motion problem using unit vectors.

Description and examples of g-forces or number of g’s.

This video is a review of Two Dimensional Vectors. This video goes over applications of vectors. 3 examples are covered illustrating how to find the resultant force.

👉 Learn how to find the extreme values of a function using the extreme value theorem. The extreme values of a function are the points/intervals where the graph is decreasing, increasing, or has an inflection point. A theorem which...

If you're given the parametric equations describing the path of a particle. How do you find out the accelerations in the normal and tangential direction? Find the velocity and you know the tangential direction. Find the acceleration and...

In this video, the teacher explains why only some right triangle hypotenuses combine to make a straight line. They demonstrate that when the ratios of the sides of two right triangles are equal, they can be placed together to form a...

Learn how to create slope fields and sketch the particular solution to a differential equation. Slope fields are tools used to graphically obtain the solutions to a differential equation. It is the estimation of the graphical...

👉 Learn how to find the point of the horizontal tangent of a curve. A tangent to a curve is a line that touches a point in the outline of the curve. When given a curve described by the function y = f(x). The value of x for which the...

Quantum coin flipping is the fairest way to flip a coin over the phone. How does it work?!

This video explains how fractional pieces that have different shapes can still be equivalent. By using cake models, the teacher demonstrates that one fourth of a rectangle and one fourth of a triangle are both equal to one fourth of a...

Join the hundreds of thousands of students that have used Mr. Clifford's videos and resources to ace your microeconomics course.

The video discusses the differences between the classical long-run aggregate supply curve (LRAS) and the Keynesian aggregate supply curve, with a focus on their shapes and shifts based on changes in factors of production.

With recent high-profile security decryption cases, encryption is more important than ever. Much of your browser usage and your smartphone data is encrypted. But what does that process actually entail? And when computers get smarter and...

In this video, the teacher explains the concept of positive and negative numbers by comparing their distance and direction from zero. The teacher uses number lines and real-life examples, such as money and temperature, to illustrate how...

Learn all about parabolas in conic sections. We will discover the basic definitions such as the vertex, focus, directrix, and axis of symmetry. We will also take a look a basic processes such as graphing, writing the equation and...

This video explains the concept of terminal velocity using velocity time graphs. The video starts with a brief recap of how the force acting on a free falling object changes over time. The video then explains how air resistance affects a...

Learning to sight read advanced piano music involves improving your skills in both horizontal and vertical sight reading. Some keyboard players tend to read individual lines from left to right on the score. This is useful for absorbing...

Now that we have dropped the ball into the bucket, we can determine the final velocity of the ball right before it strikes the bucket. Don't forget that velocity is a vector and has both magnitude and direction. Yep, component vector...

👉 Learn how to graph quadratics in standard form. A quadratic equation is an equation whose highest exponent in the variable(s) is 2. To graph a quadratic equation, we make use of a table of values and the fact that the graph of a...

Hi, everyone, I’m Audrey from Janus Academy, an established language school based in Singapore. We focus on teaching Chinese and Japanese, specialize in Chinese phonetics. Hope you find our videos interesting and educational. In this...

This nugget shows how shapes can be made to look the same by reflecting them through mirrors or rotating them through various turns.
