    non-racquet and racquet arm is an example of Newton’s third law‚ which states that every action has an equal and opposite reaction. The action of the left arm balances that of the right arm so that the racquet arm does not initiate unwanted angular momentum. As the action of the arms and torso occur the weight is shifted from the rear leg back to the front leg and the knees are bent in order to store potential energy. Notice the degree to which I bends my knees in above pictures‚ this enables my to

    NOTES Conservation of linear momentum when both objects are moving * In conservation of linear momentum the momentum of both objects before impact is not lost but remains the same for the combined momentum of both objects after impact. Example When playing snooker‚ once struck‚ the white “cue ball” will contain a certain amount of momentum. This is determined by its mass and how fast its travelling. When this ball makes contact with the black ball the total momentum of the two balls before and

    ai Allen Breed was holding the patent (U.S. #5‚071‚161) to the only crash sensing technology available at the birth of the airbag industry. Allen Breed invented the first automobile crash sensor and airbag safety system in 1968; however‚ it took several years to perfect the system (www.inventor.about.com). General Motors was the first manufacturer to offer airbags as an option for 1975 models (www.edmunds.com). In 1986‚ Mercedes Benz was the first company to install airbags in all of its models

    rocket is used as a weapon for destructive purposes‚ we call it a missile; its payload is a warhead. PROPULSION BACKGROUND Rockets are like other forms of propulsion in that they expend energy to produce a thrust force via an exchange of momentum with some reaction mass in accordance with Newton’s Third Law of Motion. But rockets differ from all other forms of propulsion since they carry the reaction mass with them (self contained) and are‚ therefore‚ independent of their surrounding

    Physics 221 Summer 2012 HOMEWORK #3 Due Monday July 2‚ 2012 1 James Bond (90 kg)‚ outfitted with perfectly matching skis and skiware‚ is at the top of a steep slope that a secret spy like him can easily handle. He lets himself go from rest and smoothly slides down the h = 15 m high hill. A big parking lot lies at the bottom of the hill. Since the parking area has been cleared of snow‚ the friction between the ground and the skis brings our hero to a halt at point D‚ located at a distance

    GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1.  The orbit of each planet is an ellipse which has the Sun at one of its foci. 2.  Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3.  The squares of the periods

    rotated by the force generated on the vanes due to the momentum change or impulse which takes place as the jet strikes the vanes. Water turbines working on this impulse principle have been constructed with outputs of the order of 100‚000 kW and with efficiencies greater than 90%. In this experiment‚ the force generated by a jet of water as it strikes a flat plate‚ conical plate‚ and hemispherical cup may be measured and compared with the momentum flow rate in the jet. 2.
