Maggie Haas Reiter Honors Physic 8 March 2015 Background Information: Anything that has mass and is moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved‚ which means that “momentum before an event equals momentum immediately after‚ or pi=pf”. Since pi=pf‚ then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi)

[Energy resources]: The 2 broad types Pros and Cons of each type Ways in which they are harnessed There two main types of energy these are: 1. Potential energy 2. Kinetic energy Potential energy Potential energy is energy stored due to position. The following are some example in which potential energy can be found. 1. Wound-up spring When a spring of a dock work toy car unwinds‚ the stored energy in the spring drives the wheels and the car moves. The wound-up spring is said to posse potential

The Energy of the Future The United States of America is in desperate need of an alternate energy source. One such alternate source is nuclear power. Nuclear power is a form of energy produced by an atomic reaction‚ which is capable of producing an alternative source of electrical power‚ replacing the energy currently supplied by coal‚ gas‚ or oil. This will help the United States move away from burning fossil fuels and potentially reduce overall pollution. Nuclear power has the potential to be

Conservation of physical resources in the Caribbean Firstly the term Physical Resource needs to be defined. According to the book Modules in Social Studies‚ physical resources are those gifts of nature such as land‚ water‚ minerals‚ forestry‚ sunlight and wind. Human beings‚ utilize these physical resources to manufacture a variety of products. Physical Resources are classified into two categories-renewable and non-renewable. A renewable resource is one which can be reinforced‚ resupplied‚ replaced

different ecosystems; each one has a powerful combination of plants‚ animals‚ and microorganism that are influenced by nonliving environmental functional units. These ecosystems are involved with human lifecycle as they furnish us with water‚ food and energy. Humankind’s relationship with the ecosystem has for a very long time been anything but a give and take situation. The ecosystem’s natural process has been altered and the added use and pollution has not helped any either. According to the

Contents[Show] The energy of an object is its ability to do work. Energy is the cause and work is its effect. Therefore both work and energy have the same units‚ which is joule (J) in the SI system and erg in the CGS system. Energy is also a scalar quantity. Energy exists in many forms. Examples Mechanical energy which is either in the form of potential energy or kinetic energy or a combination of the both‚ electrical energy‚ light energy‚ thermal energy‚ nuclear energy and sound energy etc. Potential
