This video is a lecture presentation on experiments to find the speed of waves on water. The presenter demonstrates the use of a Ripple tank to determine the speed of waves traveling across the surface of shallow water. The equipment...

👉 Learn how to find the point on the unit circle given the angle of the point. A unit circle is a circle whose radius is 1. Given an angle in radians, to find the coordinate of points on the unit circle made by the given angle with the...

Orbax and Pepper demonstrate and attempt the Mentos bottle rocket/car experiment. This video can be used as a step-by-step guide to help students create their own experiment.

Here is a practice FRQ from the 2005 AP Micro exam. Try it on your own and then go over the answers.

This video is a lecture on how to measure the distance traveled by an object using its velocity-time graph. The concept of the area under the velocity-time graph representing distance is explained, and examples are provided to...

In this video, students learn how to determine the units for their answers when using formulas. The teacher explains the importance of including units in calculations and highlights common mistakes. Through examples involving volume,...

It explains the derivation of formula to obtain the distance between two points in space. It also provides some solved examples on computing the distance between two points.

This is a lecture video on moments, which explains what a moment is and how to calculate the moment of a force. The video uses various examples to illustrate the concept of moments and how they are affected by the magnitude and direction...

In this video, the teacher explains how to find the solutions to a system of equations by graphing them and looking for points of intersection. They demonstrate that a system of equations can have one, more than one, or no solutions,...

In this video, students will learn how to find the total number of same-sized squares in a rectangle by dividing it into rows and columns. The video demonstrates different methods to count the squares, either by counting each square...

How to solve a word problem using vectors

Here I calculate the second moment of area (moment of inertia) for an I beam. The easiest way to do this is to find the moment of inertia of each of the rectangles about the I beams centroid (note you'll have to use the parallel axis...

For method of sections: 1) Draw a free body diagram of the entire structure. 2) Choose your section wisely (make sure the variables you want are part of section you've chosen). 3) Solve using static equilibrium equations (sum of forces =...

In this playlist, we discuss clinically relevant EKG patterns. This video specifically covers first and second degree AV node blocks.

In this video playlist I show you how to solve different math problems for Algebra, Geometry, Algebra 2 and Pre-Calculus. The video will provide you with math help using step by step instruction. Math help tutorials is just what you need...

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...

Given certain parameters, how would you solve this problem?<br/>
Kinetic Energy And The Work - Energy Theorem, Part 4

This video is a lesson on the concepts of scalars, vectors, distance, displacement, speed, velocity, and acceleration. It includes a quiz to test the viewer's understanding of the topics covered.

In this video series I will show you how to find the unit vector when given a vector in component form and as a linear combination. A unit vector is simply a vector with the same direction but with a magnitude of 1 and an initial point...

Remember those old space movies where spaceships had to maneuver through a bunch of asteroids scattered around and blocking the path of the ship? Well, that's not really true. The asteroid belt contains asteroids which are so far apart...
