Learn how to calculate force, work done, kinetic energy, and speed of a box being lowered. This video applies the Work-Energy Theorem to a real-world physics problem, ideal for understanding energy transformations.

This video illustrates the energy conservation principle by solving a physics problem involving a mass connected to a spring on a table, which then pulls a hanging mass via a pulley. It demonstrates how to calculate the speed of the mass...

This video explains the principle of conservation of energy by solving a problem involving a block moving on a frictionless U-shaped track. It demonstrates how potential and kinetic energy transform, allowing you to calculate the block's...

This video solves a physics problem calculating the work done by a spring force as it launches a coin horizontally, determining the initial speed of the coin. It's a great example for understanding spring potential energy and its...

This content explains how to calculate the kinetic energy of a rotating body, introducing the concept of rotational inertia (also known as moment of inertia). It clarifies that rotational inertia depends on both the mass and its...

In this video, we examine how to solve absolute value equations. We try to develop a conceptual understanding by representing the equations on a number line.

In this video, we look at two examples of absolute value equations. The first is a quadratic absolute value equation. The second is an absolute value equation with no solutions.

This video is a basic video on using the distance formula when given two points.

In this video, we do a challenging distance formula problem. We find what point on the y axis would be equidistant from two given points.

How to solve problems with bearing using trigonometry. Bearing is often used as a way of describing direction in sailing and navigation. Once you know the basic definitions and some trigonometry, you can use bearing to find direction and...

How do you maximize the volume of a box with a polynomial function? In this video, we cut the corners off a flat sheet of metal to fold up the box and create an open-top box. We model the volume of said box with a polynomial function...

How do I graph sin and cos? In this video, we use the unit circle to derive the graphs for sine and cosine. These periodic functions are very similar, but there are some slight differences.

What is the difference between linear velocity and angular velocity? In this video we will derive the formula for linear velocity (or speed) and angular velocity. Then, we will use those formulas and compare and contrast the two rates.

In this video, we will use a table to set up and solve systems of equations word problems using distance, rate, and time.

Welcome to our complete high school mathematics tutorial series! Whether you’re a student preparing for exams, a teacher seeking additional resources, or a parent helping your child succeed in math, these videos cover a wide range of...

To determine if two genes are linked, observe the variation in offspring numbers—if all genotypes occur equally, the genes are not linked. If offspring counts differ, the most frequent genotypes represent parental types, and the less...

A three-point linkage cross helps determine gene order and distances between three linked genes using observed recombination frequencies. The process involves identifying parental types (most frequent), double crossovers (DCO) (least...

To determine the perimeter of a triangle, you simply add the lengths of its three sides. Whether it’s a scalene triangle with different side lengths, an isosceles triangle with two equal sides, or an equilateral triangle where all sides...
