This video explains the principle of moments, which is the application of torque or rotational force to an object. The video breaks down the concept by discussing the anti-clockwise and clockwise moments that act on an object and how...

What is the velocity of the black just BEFORE it hits the spring? Notice that the 2 non conservative forces are your normal force and your friction force.<br/>
i) 2.56m/s
ii)0.0989m

If a disk/ wheel is rolling across a floor without slipping then the velocity of the centroid of the disk will have a velocity V_0 = Rw.

From the section: Searching in Graphs. In this section, we will see what we are searching for. Also, we will look at how to use and implement Breadth-First Search and Depth-First Search along with a simple puzzle game...

This video is a lecture presentation on orbits. It discusses how an object remains in orbit and what affects the orbital speed of an object. The presenter explains the role gravity plays in keeping celestial bodies in orbit and gives...

You should already know that velocity-time graphs look like this... and how we can use them to map out a journey.

Hey there! Looking for fun, awesome piano lessons for kids ages 6-10? Check out this video!

Your friends might believe that Physics is dry and boring, but we’re going to prove them wrong! In subtopic 1, we’ll design theme park rides, such as rollercoasters and the rotor (aka the gravitron). Then, in subtopic 2, we’ll journey...

Learn how to graph horizontal ellipse which equation is in general form. A horizontal ellipse is an ellipse which major axis is horizontal. When the equation of an ellipse is written in the general form, we first rewrite it in standard...

👉 Learn how to reflect points and a figure over a line of symmetry. Sometimes the line of symmetry will be a random line or it can be represented by the x or y-axis. Either way when reflecting a point and or figure over the line of...

In this lesson, students will learn to describe negative values using words by utilizing a number line. The concept of absolute value, which is the distance a number is from zero, will be explored through various examples, such as debts,...

What is the horizontal distance the cannon ball moves? There are a few ways to approach this problem. I personally strongly recommend applying the fundamental formulas directly rather than get used to the projectile motion formulas -...

From the section: Testing Image Classification. In this section, you will design specific security tests for image recognition systems. Here you will focus on one particular type of AI solution – image classification, and one...

Describes the working principle of a Kmeans algorithm.

In this video, the teacher explains how to calculate the average speed for two different modes of transportation by using the distance formula and solving a simple rational equation. The teacher provides an example of a scenario where a...

Learn how to graph horizontal ellipse centered at the origin. A horizontal ellipse is an ellipse which major axis is horizontal. To graph a horizontal ellipse, we first identify some of the properties of the ellipse including the major...
