Every time you see one of the CATs clearing the hill at university of the snow, you probably
don't see anything amazing about it. However, caterpillar tracks used on it are just ingenious and
its invention is comparable to the invention of the wheel.
Recoil, commonly referred to as "kick," occurs as a result of Physical properties at work.
However, it is often undesirable because it can be uncomfortable for the shooter and can reduce
accuracy. The purpose of this webpage is to discuss the physics invo
A Brief History of the Bow
* Arrowheads have been found in Africa that date back as far as 25,000 to 50,000 B.C.
* Throughout the next few tens of thousands of years, humans had PLENTY of time to refine
their techniques. Fire-hardening arrow heads, fletch
Newtons First Law
Newtons first laws states that :
"An object in motion tends to stay in motion
and an object at rest tends to stay and rest
unless acted upon by and outside force."
When in space, Newtons first law is very obvious. When an object in space
When thinking of rock climbing it is good to think of all aspects of climbing in terms of energy.
While thinking of energy, remember basic geology and know that not all rocks are formed in the
same way, in other words know what type of rock you are dealin
Paper Airplanes, flight at its simplest for humans. As kids, we learned how to build paper
airplanes and send them soaring into the sky. We didn't stop to think about why the airplanes
where able to fly after the initial thrust we gave them or how they we
Of all the pioneers of this industry, none stand out as the primary leader of discovery or
development. This competitive environment was an integral part of this field's progress. Not all
discoveries were harbored as proprietary. There was a great
Cross Country Skiing has existed since prehistoric times. The oldest pair of skis were found to be
over 4500 years old. Skiing was used as a way to travel or hunt during the winter season. The
skis were designed not so much for speed but to keep the skier
Building safe, adequate, durable roads over permafrost soil presents unique challenges to the
construction industry. It is not suprising that the mechanisms that lie behind these challenges are
explained by the laws of physics. Consequently, as concerned
Cross-country skiing is as much of a competitive sport, as it is a back country one. Cross-country
skiing is enjoyed by people of all ages, and can be relatively inexpensive. There is no need for
lift tickets and with a little maintenance equipment can la
