This physics problem demonstrates how to calculate the work done by the tension force as a cart is pulled up an incline using a rope and pulley system. It covers concepts of work, tension, and inclined planes.

This video solves a classic physics problem using the Work-Energy Theorem, demonstrating how to calculate the force exerted on a bullet as it penetrates a block and the additional distance it travels before stopping.

This video analyzes the forces and work done on a person being lifted from a cliff, breaking down the process into different stages of motion. Learn how to apply physics principles to understand a real-world rescue

Organizational Dynamics' domain is primarily organizational behavior and development and secondarily, HRM and strategic management.

With a better understanding of population ecology, we are ready to zoom out and look at community ecology, which involves interactions between species, as well as landscape ecology, which will broaden our understanding of ecosystems. How...

I have long wanted to make a video about chaos, ever since reading James Gleick's fantastic book, Chaos. I hope this video gives an idea of phase space - a picture of dynamical systems in which each point completely represents the state...

Newton’s Third Law states that for every force exerted by one object on another, the second object exerts an equal and opposite force on the first. These forces act simultaneously and are external to the system, meaning they don't...

This review of the first half of Unit 2: Forces and Translational Dynamics for AP Physics 1 covers Newton’s Laws, forces, and the center of mass. We explain how to find the center of mass for a system of particles and objects with...

Using a storytelling technique to better convey emotion in your music

This video is answering the question of what is dynamics in music.

Psychologist Philip Zimbardo (Stanford) describes the background of social unrest in 1971 that set the stage for the development of his notorious Stanford Prison Experiment.

These second-order nonlinear differential equations can be written in the form: dx/dt = f(x,y) dy/dt = g(x,y) Got a nonlinear differential equation? No problem, just linearize it! This method approximates the vector field as a linear...

These second-order linear differential equations can be written in the form dx/dt = ax + by dy/dt = cx + dy Depending on the values of a,b,c and d, the dynamics will be very different! They can be characterized by finding the eigenvalues...

Here we show another way to graphically interpret first order ordinary differential equations (ODE's) in the form dx/dt = f(x). Rather than solve the differential equation by integrating, which is often impractical, it's useful to graph...
