How Maxwell wheel works

Описание к видео How Maxwell wheel works

This is a DIY kit which gives an opportunity for the students to be familiar with Maxwell's Wheel. Here the students can see the relationship between potential and kinetic energy, linear momentum, angular momentum, nearly-elastic collisions, inertia, and torque.
Maxwell's Wheel, Experiment EXPLAINED AND PERFORMED
Introduction:

Experience momentum and conservation of energy in a stylish desk curiosity... Named after Scottish theoretical physicist James Clerk Maxwell, this scientific instrument is an intriguing demonstration of fundamental physics' concepts.

Watch with fascination as the wheel rises and falls; up and down the supporting cable until all the energy is lost to friction and it moves no more. Due to momentum and the conservation of energy, it takes longer than you might expect for the wheel to run out of steam.

Science creativity that's addictive!

Maxwell's Wheel:
Maxwell's wheel is the classic way of showing the interplay between potential energy and kinetic energy, along with the effects of nearly-elastic collisions.

Maxwell's wheel consists of an axle-mounted flywheel suspended by nylon cords at both ends. Wind it up to the top of the frame and let it go!

As it drops, gravitational potential energy changes to the kinetic energy of the wheel's descent and rotation.

The jerk when the wheel reaches the bottom reverses the linear momentum causing the wheel to wind back up.

A small amount of energy is lost each time due to the friction of the nearly-elastic collision that occurs when the wheel jerks at the bottom.

When it has unwound to the bottom, the sharp jerk on reaching the end of the nylon cords reverses its linear momentum (while maintaining its angular momentum).

This "collision" at the bottom is nearly elastic - some of the kinetic energy is lost.

The ratio of energy kept to starting energy tells you how "elastic" the collision was through its coefficient of restitution.

Is this wheel defying gravity?

We will demonstrate the relationship between potential and kinetic energy, linear momentum, angular momentum, nearly-elastic collisions, inertia, and torque.

Studying the conservation of energy is unforgettable with this mesmerizing demonstration!

Dynamics of Maxwell's Wheel

The aim of this experiment is:

1. To study the combination of rotational and translational motion in Maxwell's wheel.

2. To understand the principle of conservation of energy and how it is distributed among the translational and rotational motion.

In the translational motion of an object, the entire object can be considered as a single point.
• All points of the object move in similar fashion and hence can be described by the same equation of motion.

Rotational motion is slightly more complicated than translational motion.
• Rotating objects cannot be replaced by a single point as simply as it is done in translational motion.
• Different points on the object are moving with different speeds, depending on their distance from the axis of rotation.

Note : • Please be gentle, careful while assembling. Apply your creativity while assembling.
• All of Topsun products are unique and handmade. We work with designs and Endeavour to create such products. However, the very nature of being individually designed by hand gives a raw finish to the projects since it should appear that students have created the same on their own.

Each product under YouDo banner is a result of painstaking research by well-qualified R and D team. We cater for requirements for all segments of society keeping in mind their requirements, their needs and their budgets. Each of our product contains a user manual which is written in an easy to understand manner making use images graphics and schematics where required.
Last But not the least when we manufacture any product we keep in mind to use
Eco- friendly material and most of our products are eco-friendly. All of our products are curriculum based.
