Delta Force

Bai and Sun's sandwich beam theory was the consideration of the transverse, longitudinal, and rotatory inertia all in one set of equations. The sandwich beam dimensions used by Bai and Sun are shown in Figure 1. Fig 1:Three Layer sandwich beam Assuming that the face layers are elastic and behave as Bernoulli-Euler beams, with negligible shear deformation, the longitudinal and transverse displacements and at any point within the face layers may be

laws with the rocket launches we had. Newton’s first law is the law of inertia. The full statement is: “Every object continues its state of rest or a state of motion in a straight line at constant speed unless it is compelled to change that state by forces exerted upon it.” Inertia is the property of objects to resist change in motion. When I throw a coin up in the air in a speeding car, it falls in where I threw the coin, not speeding back with the car. It is because the coin has inertia, which resists

“Our attitudes control our lives. Attitudes are a secret power working twenty-four hours a day, for good or for bad. It is of paramount importance that we know how to harness and control this great force.” -Tom Blandi Values can either be transmitted or acquired. It is anything that we put importance on. It comprises all the behaviors, attitudes and cultures one is into. Sometimes, we are confused if values are how we deal with people but realistically speaking, it is how we deal with our environment-

interactions to explain friction and when asked to explain microscopic friction the majority referred to their “interlocking-intertwining” or “rubbing-hitting” models. Most agreed friction is the force required to move atoms over bumps and valleys because of intertwining and interlocking of the atoms or friction is the force caused by the rubbing and sliding of an atom past another. Also when the students with the interlocking model were question about the outcome if the surface was to become automatically

Air Trajectory: Gravitational Energy and Projectiles Brian Kim and Andrew Lee Centreville High School Abstract Science Olympiad is set up as a competition in the same way a track competition is set up. Competitors extensively train for each of their events for several months beforehand in order to perform well on competition day. There are 23 events that cycle through each year to accurately represent the scientific challenges society faces today. For example, there are many events for renewable

relationship between the body and the forces upon it, and it’s response to the motion. Sir Isaac Newton was one of the greatest scientists and mathematicians that ever lived, born in England on December 25, 1643, the same year that Galileo died. He went to Trinity college in Cambridge. While he was in college, Newton had new ideas about motion, which he called Newton’s three laws of motion. He also had ideas about gravity, the diffraction of light, and forces. His ideas were so great that in 1705

a net force. Sometimes this law is referred to as the law of inertia, where inertia is explained as being the natural tendency of an object to remain at rest or in motion at a constant velocity. The second law states that: when a net external force acts on an object of mass m, the acceleration that results is directly proportional to the net force and has a magnitude that is inversely proportional to the mass. The direction of the acceleration is the same as the direction of the net force. Lastly

it means that for every action there is a reaction, which is equal to the magnitude of the force applied but opposes the direction of the action.

every action there is an equal and opposite reaction. The blade applies force on the ice and the ice pushes back on the blade causing a forward movement. To accelerate, players exert a strong force on the lower part of their bodies by leaning forward. “Gravity pulls down on a hockey player's center of mass which ‘torques’ him forward” (Exploratorium 1). Skaters also skate and accelerate while turning. Centripetal force enables the player to lean inward and create a sharp turn (Haché 50).
