This content defines torque for a particle moving along any trajectory relative to a fixed point, not just a fixed axis. It establishes torque as the vector cross product τ=r×F, explaining its direction using the right-hand rule and its...

This content introduces the concept of torque as the twisting or turning force that causes rotation, explaining its dependence on the applied force and the perpendicular distance from the axis of rotation. It delves into calculating...

This content defines angular momentum (ℓ) for a particle as the cross product of its position vector (r) and linear momentum (p), i.e., ℓ=r×p=m(r×v). It clarifies that angular momentum is a vector quantity defined with respect to a...

Learn the basics of vector physics, including how to add vectors and interpret their graphical representation. Understand the difference between scalar and vector quantities with real-world examples.

How do you write the linear combination of unit vectors? How do you write the unit vector in the same direction as a given vector? What are the standard unit vectors? This video answers all of these questions and tells you all the basics...

How do you add vectors, subtract vectors, and use a scalar on vectors? This video shows how to do all of these vector operations both algebraically and graphically. This video is for a precalculus class

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

We've learned about matrix diagonalization, which is a type of matrix decomposition. There are some others that we must learn, including LU decomposition, Cholesky decomposition, QR decomposition, and singular value decomposition. Let's...

We've looked at a few simple examples of first-order differential equations and how to solve them. Now let's take a look at exact first-order differential equations.

Vector databases are rapidly growing in popularity as a way to add long-term memory to LLMs like GPT-4, LLaMDA, and LLaMA. Learn how popular vector databases like Pinecone and Weaviate can store ML embeddings to integrate with tools like...

In this video, we will work on the transaction class and add reporting to our ATM system.

This video demonstrates the multiplication of a parallel matrix in the naive or basic way.

Unlock the power of text manipulation in R with the str_locate() function from the popular stringr package, part of the Tidyverse ecosystem! In this beginner-friendly tutorial, we'll walk you through how to precisely locate substrings...

The tangential velocity is measured at any point tangent to a rotating wheel. Thus, angular velocity, w, is related to tangential velocity, Vt, through the formula: Vt = wr. Here, r is the radius of the wheel. Tangential velocity is the...

En este vídeo vamos a hablar sobre las fuerzas de contacto que podemos encontrar en nuestro día a día, así como de las fuerzas fundamentales y de los sistemas ligados y algunas consideraciones que debemos recordar a la hora de estudiarlos.
