of momentum and conservation of energy as well as motion of projectiles. Carbon Paper Meter Stick         Ballistic Pendulum                                             In this experiment a steel ball will be shot into the bob of a pendulum and the height, h, to which the pendulum bob moves, as shown in Figure 1, will determine the initial velocity, V, of the bob after it receives the moving ball. If we equate the kinetic energy (KE) of the bob and the ball at...

Wind Energy A turbine is machine that spins arounds catching energy that's passing by. The huge rotor blades (propellers) on the front of a wind turbine are the "turbine" part. As wind passes by, the kinetic energy (energy of movement) it contains makes the blades spin around (usually quite slowly). The blades have a special curved shape so they capture as much energy from the wind as possible. Although we talk about "wind turbines," the turbine is only one of the three...

Biomass Energy

Biomass Energy Introduction Biomass is biological material derived from living, or recently living organisms. It mostly often refers to plants or plant-derived materials which are specifically called  lignocellulosic biomass. As a renewable energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel.  The source of biomass energy. Wood energy. is the largest...

Energy Conversation States

of the item. (c) (i) The energy on impact is calculated by using the following equations: Potential Energy (PE) = mass x gravity x height This gives the potential energy at the height when the ball is held at the start of the test. This can be used as a check to for the Kinetic energy (KE) equation as the law of energy conversation states that energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant. So the...

Energy Crisis

might not be able to get out of. If the pursuit of energy continues in the direction it is going, more and more problems will arise and inhibit the everyday lives of society while increasing the risk of major disasters inflicted by big energy companies. In the article, “The Coming Era of Energy Disasters” written by Michael Klare, Klare says, “As long as the industry stays on this course, rather than undertaking the transition to an alternative energy future, more such catastrophes are inevitable,...
