Walking involves a cyclic exchange of gravitational potential energy and kinetic energy of the center of mass. Our goal was to understand how the limbs of walking quadrupeds coordinate the vertical movements of the fore and hind quarters to produce these inverted pendulum-like movements. We collected kinematic and ground reaction force data from dogs walking over a range of speeds. We found that the fore and hind quarters of dogs behaved like two independent bipeds‚ each vaulting up and over its

Investigatory Project in Physics Submitted by : Jay Loteyro Anecito Trongcoso Submitted to: Ms. Matilde Macawile Balloon Powered Car When it comes to powering a race car‚ there are a ton of different options. Some cars are powered by gasoline‚ diesel‚ or other combustible fuels‚ or you can even power miniature race cars using a mousetrap! In the Balloon Powered Car‚ we’ll show you how to build a racer that uses the power of air pressure to roll across a room. Objectives:

Project 1: 1. Results for a: ht=500/ spd=0mph —too slow! Satellite crashed into Earth! Results for b: ht=500/ spd=100mph —too slow! Satellite crashed into Earth! Results for c: ht=500/ spd=25000mph —too fast! Satellite left viewing area and took off in space somewhere! I was determined to get a 100%‚ so I played around with the numbers until I found that at 500 miles above the Earth‚ the satellite would have to be launched at 16‚700mph in order to reach a perfect orbit. Below is the explanation

WAVE ENERGY Chapter 2: Energy Technology 2.1 Source of Wave Energy Ocean waves are caused by the wind as it blows across the open expanse of water‚ the gravitational pull from the sun and moon‚ and changes in atmospheric pressure‚ earthquakes etc. Waves created by the wind are the most common waves and the waves relevant for most wave energy technology. Wave energy conversion takes advantage of the ocean waves caused primarily by the interaction of winds with the ocean surface. Wave energy is

If we don’t replenish our supply‚ we run the risk of ill health. There is a that theory mentions that the length of life is inversely proportional to the rate of exhaustion of the enzyme potential of an organism. The increased use of food enzymes promotes a decreased rate of exhaustion of the enzyme potential." In other words‚ the more food enzymes you get‚ the longer‚ and healthier‚ you live. As food enzymes are destroyed at temperatures above 118 F processed foods contain few‚ if any enzymes

the 2 balls‚ the bucket with water and the dominoes. 2. To change a thermos into an open energy system is by opening the lid. 3. Energy is never created or destroyed; it is just passed on to other different types of energies‚ like potential to kinetic or potential to mechanical energy. 4. One place is where the dominoes fall and push the first ball. The second is when the bucket full of water pulls down the string to open the lid of the cookie

The Neuromuscular Junction by: Dominique Latham 651 words A neuromuscular junction is a place in the body where the axons of motor nerves meet the muscle‚ thus transmitting messages from the brain which cause the muscle to contract and relax. Every organism has thousands of neuromuscular joints which are the locations and means by which the motor neuron of the nervous system that instructs the muscle cells of the muscular systems to take action. Action that ‚ in turn lead to movements of muscles
