In this video Paul Andersen explains how the mechanical energy added or removed from a system results from work. For work to occur a force must act parallel to the displacement of the system. Since work and energy are equivalent the...

Discover how mechanical energy—kinetic plus potential—remains conserved in systems under conservative forces. With real-world examples like roller coasters, this lesson simplifies a core law of classical mechanics.

Learn how to derive gravitational and elastic potential energy using the work-energy principle. Understand how conservative forces store and transform energy in physics systems like springs and gravity

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.

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 demonstrates how to calculate the net work done on an object by multiple forces and explains its relationship to the change in kinetic energy. It walks through a solved physics problem, ideal for understanding work-energy...

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 provides a step-by-step solution to a physics problem, demonstrating the application of Newton's Laws of Motion and kinematic equations to calculate force, distance, and work done for an object under constant deceleration

What's work? Not that place you go to earn money. In physics it means something else. And what's energy? Not like in the groovy sense. Actually, energy is one of the most improperly used words in the English language. Let physics define...

This video provides a clear and concise explanation of the scientific definitions of work, power, and energy, and how these concepts are interconnected. It covers the formulas for calculating work and power, as well as the relationship...

You can put energy into an object. Wanna know how? No, you don't need a Harry Potter wand. Just lift it up above your head! By doing so, you bestow the object with more potential energy. Learn more about the energy of motion and the...
