Air Force Base

bottle rocket is compressed air as it is pumped into a soda bottle, half filled with water by a bicycle pump. Compressed air is an excellent source of energy because it is very lightweight and can store a plentiful amount of energy, also it does not weigh down the rocket. Water is then used as the fuel for the rocket. Water is very dense and provides a lot of inertia for the rocket to propel upwards as water is pushed out the bottom of the rocket due to the compressed air. Newton’s First Law of…

Unit Three: Energy Our universe is made up of matter and energy. Matter is made up of anything that has mass and takes up space where energy allows the ability to do work or have the ability to move or elicit change in matter. In other words, energy is a property of objects which can be transferred to other independent objects or be converted into different forms. It is described as “a system to perform work.” We have two different types of energy; kinetic and potential energy. Kinetic energy is…

because the wings cause lift. The lift of the wing has to be greater than the amount of gravity that is pulling down on the plane. The wings cause lift because of an airfoil shape. The wings are rounded on the top and almost flat on the bottom. The air has to go farther over the top of the wing so there is a low pressure area above the wing. This causes the lift of the wing and holds the airplane in flight.…

ways to simulate the feelings of live combat and have similar features. In order to begin feeling the adrenaline rush flow through your veins you need to have the right equipment. The basic equipment for playing paintball: marker(paintball gun), air tank, hopper, and paintballs. These are the most important elements to begin playing paintball and are going to be more expensive. For safety it is important to have certain clothing and…

The same rules apply, gravity is pushing the marcher down and the ground is pushing back. Same with friction, friction keeps the movement steady and momentum determining how fast and how far the movement will take the marcher. This time there is force. As stated, instead of a lift there is a push of the foot giving more momentum to the movement. This can make the marcher go farther or faster but it does depend on how much push you give. You will receive an equal and opposite push back from the…

The force of gravity is a force which means that any work done by it does not change the mechanical energy of the carts. The normal force of the track pushing up on the cars is an external…

4.1 Strength of Anisotropy “The strength of anisotropy is calculated by the “kern and Richter” formula which gives the magnitude anisotropy k= (Vmax –V min)/Vmean, where Vmax and Vmin are maximum and minimum velocity. For P wave in the olivine crystal Vmax and Vmax are 9.89 and 7.72km/s respectively, so strength of anisotropy is 25%. For S wave k= 22% for Vmax and Vmin are 5.53 and 4.42 km/s respectively” [Seth stein 2003]. This anisotropy is the intrinsic anisotropy of the material defined as…

dropped I probably got the wrong height of the balls bounce. Bounce meaning the quality of a substance that is able to rebound. When you throw a ball on the ground it bounces right back up to you because when the ball hits the ground it puts an equal force back on the ball. Balls are made out of a rubbery elastic material, meaning they can…

velocity. In this place, you also have a large amount of air resistance acting on you due to friction and your direction. During this part, you experience high G-forces acting on you due to your position. Once you are down the mountain, you are lifted towards a loop. In this loop, you are experiencing a centripetal force, or the force an object moving along a circular path to move toward the center of the path. You experience a large g-force in this loop due to your position upside down. When…

One of the most important activities of science is measurement. Measurement is a means of quantifying properties for identification. For example, density is the relationship between the mass and volume of a pure substance. One could determine if a piece of yellow metal is gold by determining its density. Measurement allows scientists to make comparisons. Measurement also provides a means by which scientists can judge the reproducibility of an experimental procedure. However, measurement is not…
