Key Air Force Leadership Message Briefing INTRODUCTION Attention: How many of you every time you use the restroom you remember to cut off the light? Purpose/Motivation: I’m standing her to brief you about Energy Awareness in the Air force not just cutting off the lights when you leave a room but a Multidimensional approach to energy efficiency Overview: I’ll cover our main mission which is to fly, fight and win in the air, space and cyberspace, our Air Force Facilities, and the overall

critical angle between two different surfaces in contact on an inclined plane. It aims to determine the coefficient of static friction between two surfaces in an inclined plane by measuring the critical angle θc, the steepest angle of incline in which the mass in contact does not slide. This paper also aims to show the relationship between the materials in contact and the effect of their masses to the critical angle θc. The experiment also shows the accuracy of using Newton's second law in measuring the

run so we can watch our favorite shows. According to Webster dictionary, physics is the science of matter and energy and of interactions between the two. In all physics consists of energy, kinetic energy, potential energy, velocity, acceleration, mass, force, and gravity. Without physics many things would not be possible. In fact, when a person is driving their car they are suing momentum (the quantity of motion of a moving object) and acceleration. Over time our general understanding of

smaller arc to travel through. Because the distance the mass travels from maximum displacement to equilibrium is less while the acceleration of both pendulums remains the same, the shorter pendulum will have a shorter period. Mass vs. Period: The graph done in class can show how the change in mass does not affect the period. An example that can demonstrate this kind of behavior is when the bobs of two pendulums differ in mass, the heavier mass provides a larger restoring force, but it also needs

To day doctors are using Body Mass Index as the guide lines. One pound of body fat is same as one pound of butter. You can buy various kind of butter with calorie level of 3000 to 3600. 1500 to 1800 is very low daily intake. Most show 2000 to 4000. Again each individual is different, it depends on the metabolism of the individual. Say a person needs 2000 calories per day, and a person is over weight by 20 pounds only. Then by reducing the intake by 200 calories it will take him 15 to

Whale Rider was a movie produced in 2003, and it is about a girl named Paieka, or Pai. She is the granddaughter of Nanny Flowers and Koro. In the beginning of the movie, Koro has a good relationship with Pai. He brings her to school everyday by giving her a ride on his bike, and everything is good between them. Later on in the movie, Koro is worried about the rest of his people since they are drifting away from the traditions. People are smoking, the men are drinking and shooting pool, and the

Practice: Vary track angles, release heights, and cart masses. And then release the cart form the rest. During each trial, measure the time when the cart reaches to bottom of the incline. 2. Vary release heights: Set the track angle which is 4.9° and the mass which is 190g. Release

three different masses (AVOID CHOOSING THE SAME MASS USED BY OTHER STUDENTS) . By clicking the button “Push”, you will produce a speed vs time graph (do it for three different masses), and then use F = ma to calculate the acceleration for each mass. Record the mass and acceleration values in the table below: |Mass 1 = 120 |a1 =.83 (100/120) | |Mass 2 = 180
