    Delta Force During the 1970’s the United States became the favorite whipping boy for any terrorist group that was worthy of bearing the name. They had realized that American interests throughout the world could be struck at with little or no retaliation. At this point in the century America had sickened of warfare in Vietnam and was both unwilling and unable to strike back at the pests of terrorism. Our government did little more than apply Band-Aids to wounds while ignoring the infection

    Purpose To be able to understand and verify the relationship centripetal force‚ mass‚ velocity‚ and the radius of orbit for a body that is undergoing centripetal acceleration. Background Information An object moving in the same direction is not necessarily undergoing acceleration. If the object changes speed while moving in the same direction there is acceleration (or deceleration). On the other hand‚ if the object moves at a constant speed in the same direction‚ there is no acceleration

    Force‚ Motion‚ Newton’s Laws‚ Momentum‚ and Impulse What is forceForce is a push or pull upon an object resulting from the object’s interaction with another object. There are two types of force‚ contact forces‚ and forces resulting from action-at-a-distance. A contact force can be frictional forces‚ normal forces‚ applied forces‚ and air resistant forces. The formula for contact force is F = ma. This type of force occurs when two objects are contacting each other physically. If you kick a ball

    there is an equal opposite reaction." The characteristics to explain that an Action Force results in a Reaction Force are that the two forces should be equal in magnitude. The two forces are in opposite directions. The action force is applied to an object and reaction force is applied to something else. For example‚ a closed balloon shows all the forces are equal in magnitude‚ the gas inside the balloon. The two forces in the opposite direction

    Alixandria Zeidel Physics 131 – section LZ Hasbrouck 208 10/01/14 Forces and Newton’s 2nd law Abstract The purpose of this lab was to learn about how force influences acceleration. A hanging mass is tied to a frictionless glider and the mass is dropped. While the glider is being pulled by the mass it is possible to measure to tension force on the rope between the two objects. A motion sensor graphs the movement of the system and from the slope it is possible to calculate the acceleration of both
