the ground has more mass than the player‚ causing the player to bounce up slightly‚ causing motion in his brain. Overall‚ football related concussions can be illustrated through an understanding of Newton’s 1st law of motion‚ the Law of Conservation of Energy‚ and Newton’s 3rd law of motion. If we look at football through the eyes of science‚ we see how dangerous it really is. Scientists are still figuring out ways to help stop concussions and understand them better. But by using basic laws of

Energy Lab On November 13th‚ we did a lab to learn about energy. The definition of Kinetic Energy is energy of movement. The definition of Gravitational Potential Energy is energy in an object due to its positioning. The question that we had to answer was whether of not we could calculate the Gravitational Potential Energy and Kinetic Energy of various objects in different locations. To do this lab we had to first weigh the given objects. For this time‚ we weighed : a marble‚ a bouncy ball‚

WAVE ENERGY Chapter 2: Energy Technology 2.1 Source of Wave Energy Ocean waves are caused by the wind as it blows across the open expanse of water‚ the gravitational pull from the sun and moon‚ and changes in atmospheric pressure‚ earthquakes etc. Waves created by the wind are the most common waves and the waves relevant for most wave energy technology. Wave energy conversion takes advantage of the ocean waves caused primarily by the interaction of winds with the ocean surface. Wave energy is an

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

Running Head: Energy Conversion Energy Conversion Marlon Walker Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar

The North American Model of Conservation is an important part of the preservation and conservation of our nation’s natural resources. The model contains seven main tenets‚ each of which serve to provide opportunity for our use of the wildlife resources while simultaneously protecting the same resources from over harvest. The ideas presented in this model have been present long before the words were put to paper; some can be traced back to Roman times. The tenets began to become more concrete in the

Energy is a very important factor that determines how far the cars I made for my project will go. This illustrates how if the car doesn’t have enough kinetic energy the car won’t go very far. According to my research‚ If work‚ which transfers energy‚ is done on an object by applying a net force‚ the object speeds up and thereby gains kinetic energy(Kinetic Energy) which will make
