Application of Energy ------------------------------------------------- Forms of energy Main article: Forms of energy Energy exists in many forms: Heat‚ a form of energy‚ is partly potential energy and partly kinetic energy. In the context of physical sciences‚ several forms of energy have been defined. These include: * Thermal energy‚ thermal energy in transit is called heat * Chemical energy * Electric energy * Radiant energy‚ the energy of electromagnetic radiation *

wheel the kinetic energy has two components‚ translational due to the bodily movement of the mass centre down the slope and rotational due to the wheel spin. Now the source of this energy is the loss in potential energy as the wheel moves down the slope. If it is reasonable to assume that friction effects are insignificant then no energy is lost. Thus the loss in potential energy becomes a gain in kinetic energy. Hence‚ Loss in potential energy = mgh‚ is equal to the (1) Gain in kinetic energy

way softball works and why it works. Momentum Running: When running the bases in softball‚ there is a lot more to it then the average person would think. While we run the bases‚ we are changing our momentum by applying more force‚ the force of friction‚ onto the ground which causes more force exerted on us because of Newton’s 3rd law. Applying more force in turn increases the base-runner’s velocity. Catching: When catching a fly ball or grounder‚ it is best to move with the ball and not catch

Describe and explain how river processes change along the long profile of a river A river changes shape as it flows from its source (where a river starts) to its mouth (where a river flows into a sea or lake). The shape of the long profile (a slice through the river from source to mouth) shows how the rivers gradient‚ height‚ energy and load changes due to erosion processes such as abrasion‚ cavitation‚ attrition‚ hydraulic action and corrosion as well as how the rivers deposition rates fluxuate

remediation. AMD prevention is a key requirement for meeting mine closure standards and AMD prediction plays an integral role in waste management and AMD prevention. However‚ both the static and kinetic tests used currently have shortfalls‚ including only providing a worst case scenario‚ providing limited kinetic data‚ particularly with respect to microbial catalysis or requiring an excessive time frame for the provision of useful data. In this study‚ we review biological tests reported to predict
