Jessi and Squeaks just got a new telescope, and they can't wait to check out the night sky! But there's just one problem: it's too heavy to bring up the stairs into the observatory! Join them as they learn about a simple machine that can...

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 walks through a numerical problem involving rotational motion, specifically calculating acceleration, angular acceleration, and tension in a system with a falling block and a rotating pulley

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...

In this video, students will learn about six simple machines: lever, inclined plane, wedge, wheel and axle, pulley, and screw. They will understand the basic principles of how these machines work and how they can make our lives easier by...

A 55 g mass is attached to a light string, which is placed over a frictionless, massless pulley, and attached to a 199 g block which is on a board inclined at 39.3° as shown. Assuming the block starts at rest and the μk between the...

This designs uses pulleys to increase the turning force (and reduce the speed) of the driven axle. A very small pulley is fitted to the motor and a larger pulley to the axle - connected together with an elastic band. The design features...

A basic guide to using pulleys to make moving toys and models in schools plus a demonstration showing how they can be used to create mechanical advantage.
