Some curious real experiments

[John Goodman]

The link below describes a few simple experiments, which break the law of conservation of mechanical energy and the law of conservation of linear momentum. You can easily carry out these simple experiments in your garage as many times as you want.

IMPORTANT NOTE 1. It is highly recommendable that the above mentioned experiments are evaluated and realized by a highly qualified expert (Ph.D.) in theoretical and applied mechanics. Otherwise nothing will come of it (most probably).

----------------------------------------

IMPORTANT NOTE 2. The key question in the above mentioned experiments is how to reduce standard friction (where necessary) to a certain minimum limit, beyond which the experimental error (due to friction) is small enough and can be neglected. The answer is simple. You can use for example permanent magnet slides as shown in the link https://www.youtube.com/watch?v=NoW0A8hYs5A . (Permanent magnet slides reduce friction practically to zero and the measuring devices do not register any force of friction.) Alternatively you can use hundreds of other methods for reducing of friction (as much as necessary) as modern technologies allow this feat. We live in 21st century after all.

Looking forward to your comments after repeating the above mentioned simple experiments.
