Fear is in everyone's life, but this fear may vary from one person to another, and it depends on the situation that that person is in. my experience with fear happened to me when I was in Saudi Arabia and. I was only 16 years old when this incident happened. I was driving my car on a highway in Riyadh the capital city of Saudi Arabia when suddenly I saw a car braking in front of me after that he turned very quick and I could not see in front of me because there was a lot of dust and smoke. Then I hit a car that had crashed in a lighting pole, after that everything went dark and I can smell the gasoline and the airbag smoke I really thought that the car is going to catch fire, so I panicked and tried to get out of the car as soon as possible, when I got out of the car I laid on the sidewalk and couldn’t breath because of all the smoke that I inhaled. Finally when I got up I walked to the car that I crashed into and saw two men lying on the ground and heavily bleeding, that moment was the scariest moment of my life because I really thought that they will die and I will be in real trouble. After the police came it turned out that they were D.U.I and they have hit one other car before I crashed into them, after that the ambulance came and took them they were badly injured they had multiple broken bones and cuts and I had minor injuries. Finally I learned from this incident that no one ever should drive while drunk because it's going to result in very…

What is energy? According to Mirriam-Webster.com, energy is usable power that comes from heat, electricity, etc. Where do we get this usable power? Most of the heat and electricity we use comes from sources that are neither renewable nor sustainable. "The First Law of Thermodynamics states that energy can neither be created nor destroyed: it can only be transferred or changed from one form to another." What does this say about he current energy crisis affecting the world today…
Energy works all in different ways, whether when you wake up with full boost of energy to go for a run or just turning on a light bulb. There are plenty of other things we need energy but most wasn’t able without someone designing it or creating it. Which is why we have energy workers, these people day by day find source full ways to supply us with energy. They every year come up with ways to help save energy but still be the same amount you did the year before. Life wouldn’t be the same without…

Petroleum Poses Precarious Problems Presently
The world’s energy crisis is here and it is a problem that will not go away unless action is taken to correct the damage that has been done. Facts only do justice to the predicament that has been caused by excessively using Earths natural resources. In the years before coal and fossil fuels being used as a primary resource of energy the Earth was in equilibrium and the thought of climate change was nonexistent. The world is responsible for consuming…
Chemical potential energy: stored energy.
4. Chemical energy: potential energy stored in chemical bonds or compounds
5. Displacement: vector quantity that measure change in distance, direction or position of an object.
6. Distance travelled: scalar quantity that measure how far and object has moved.
7. Efficiency: ratio of how useful work output to the total work input.
8. Elastic potential energy: energy stored in an object that has it shape changed by stretching.
9. Electrical energy: work done by…
Potential Energy Roller Coaster Lab Report
Madeline Ware p5 Nov. 20, 2013
Starting with this lab we constructed a ramp or a 'roller coaster' that would be able to let our marble go from the top of the table, down to the floor. The purpose of this study was to be able to find the kinetic and potential energy of a marble going through a twisted ramp through finding weight, height, time, and velocity. The original question was asking to find ot the kinetic and potential energy of the…
friendly energy company. We shall specialize in alternative energy and cleaner ways to achieve our energy needs through solar, wind, hydroelectric, and geothermal energy. With the cost of fuel and profits of foreign oil it will be beneficial to have domestic energy, thus creating jobs and cutting back energy costs and less pollution.
2. The energy market is controlled by Oil Companies and other energy methods are uncommon on as large of a scale as our company.
3. Environ-G will be a clean energy company…
Whenever you conserve energy you not only save money, you also reduce the demand of fossil fuels such as coal, oil, and natural gas. Less burning of fossil fuels also means lower emissions of CO2, the primary contributor to global warming, and other pollutants.
Energy Conservation refers to reducing energy consumption through using less of an energy service. Energy conservation doesn’t differ from efficient energy use, which refers to using less energy for a constant service. This means…
P6: TYPES OF ENERGY
WHAT IS ENERGY?
The ability to do work is known as energy. There are different types of energy:
1. Mechanical: Mechanical energy can either be kinetic energy or potential energy. E.g.
A moving car possesses mechanical energy due to its motion (kinetic energy). This energy is then mainly converted to kinetic energy and some wasted as sound and heat energy.
Mechanical energykinetic energysound and heat energy
A drawn elastic band posse’s mechanical energy due to its stretched…
Today: Energy (Chapter 2)
• Contrast the general properties of the different
forms of energy.
• Articulate the difference and relation between
Energy, Power and Work.
• Compare the concepts of Temperature with Heat.
• Examine the implications of the laws of
Thermodynamics in our lives.
• Explore possible sources of energy for our society.
• Doing anything requires energy
• Everyday life “energy” = exuberance
• Physics takes it more seriously:…
