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 video provides an introduction to pulleys as simple machines. The video describes the basic components of a pulley and distinguishes between two main types of pulleys: fixed pulleys and movable pulleys.

In this video, we learn about three types of simple machines: levers, wheel and axle systems, and pulleys. The different types of levers are explained, as well as the mechanical advantages of each. We also learn about the different types...

A day does not go by without using simple machines. This program explores the six major types of simple machines with practical, colorful examples of each. Vivid video footage illustrates how each of the following simple machines works...

If a pulley system is accelerating, then the tension in the cable is constant IF

1) Pulley is mas

This live-action video program is about the word pulley. The program is designed to reinforce and support a student's comprehension and retention of the word pulley through use of video footage, photographs, diagrams and colorful,...

If a pulley is in static equilibrium and the following is true:

1) Rope is mas
sless
2) Pin is fr

ictionless

Then the tension in the cable will be constant everywh

Mass 1 and mass 2 hang from either side of a frictionless #pulley with #rotationalInertia, I, and radius, R. What is the angular acceleration of the pulley? Use #ConservationOfEnergy

Angular momentum is used to determine the acceleration of a pulley mass system. two alternate solutions are shown, and the acceleration is demonstrated. This is an AP Physics C: Mechanics topic.

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...
