    Newton ’s laws of motion  Newton ’s laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries and can be summarized as follows: 1. First law: The velocity of a body (a state of rest or of uniform motion in a straight line) remains constant unless the body is compelled to change that state

In the first phase of the triple jump‚ the competitor builds momentum by sprinting down the runway‚ planting their lead foot at the marked board‚ and “hops” into the air‚ cycling one leg around into phase two. After completing the cycle‚ the lead foot strikes the ground again initiating the “skip”‚ where the opposite

    rotated by the force generated in 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. 2.0 Experimental Design

    The Pelton wheel is a water impulse turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water‚ as opposed to its weight like traditional overshot water wheel. Although many variations of impulse turbines existed prior to Pelton ’s design‚ they were less efficient than Pelton ’s design; the water leaving these wheels typically still had high speed‚ and carried away much of the energy. Pelton ’s paddle geometry was designed so that
