A kinetic energy penetrator (KE penetrator) is a weapon that damages a target by slamming into it at high speed using kinetic energy. The most common form is the armor piercing fin stabilized discard sabot (APFSDS), used to penetrate tank armor. The US military developed a flechette-based rifle for soldiers, but it never performed well […]
Radiant energy is energy from electromagnetic waves, measured in joules. It can be viewed as energy stored in photons or carried in oscillating magnetic and electric fields. It is used in open systems, photosynthesis, solar energy, radiant heating, and medical treatments. Nikola Tesla was a pioneer in studying radiant energy, and it is an abundant […]
Strain energy is potential energy stored in a solid when it is deformed and released when it returns to its original shape. The energy is equal to the amount applied to the object, except when it exceeds the plastic strain point, causing permanent change. A simple example is a spring. Strain energy is a form […]
Hydrogen is a viable source of energy due to its abundance and lack of toxic emissions. It is harvested from compounds through methods such as electrolysis and steam reforming, and stored in tanks before being used in fuel cells or batteries. Hydrogen energy is used in space shuttles, cars, buses, trains, and even rural hospitals. […]
Potential energy is stored energy that can be released, while kinetic energy is the energy of motion. Gravitational potential energy can be calculated using the formula GPE = mgh. When an object is released, its potential energy is transformed into kinetic energy. Conservation of energy states that energy cannot be created or destroyed. Kinetic energy […]
Solar thermal energy uses the sun’s heat for various tasks, including food preservation, cooking, and generating electricity. It can also be used for cooling through evaporative cooling. This form of energy is accessible to communities worldwide and can operate 24/7 with supporting technology. Solar thermal energy is a form of energy where the sun is […]
Geothermal energy uses heat from the earth to generate electricity, but has three main disadvantages: renewability, infrastructure requirements, and location. Drainage of resources is a major drawback, and the equipment and personnel needed represent a significant investment. Geothermal energy can also affect soil stability and tectonic plates. Further exploration is needed before it can be […]
Solar energy equipment includes thermal systems for heat and electricity production, and photovoltaic cells for direct electricity generation. Building-integrated and standalone devices are used for various applications, while solar power plants generate large amounts of electricity. The different types of solar energy equipment include a large variety of devices that trap solar energy and convert […]
A master’s degree in energy economics can offer many opportunities, with global clean energy spending predicted to reach $1 trillion by 2020. Consider the area of specialization, courses required, and additional training in related fields. Many schools offer this degree, and additional training can be found at seminars or symposiums. Those who are concerned with […]
Anti-energy drinks, such as Slow Cow and Drank, contain natural herbs like chamomile and valerian root to induce calmness and relaxation. However, concerns exist about their effectiveness and potential side effects. The market for these drinks may grow in the future. The introduction of so-called “energy drinks” created quite a stir in the beverage industry, […]
Molecules can coexist peacefully or cause reactions when brought close together with activation energy. Heat and enzymes can activate molecules, with enzymes being biological catalysts that lower activation energy. Enzymes have active sites that bind to substrate molecules, making it easier for them to react and release energy. The activation energy barrier prevents unstable reactions […]
Nuclear power is efficient, cheap, and produces less air pollutants than traditional power plants. Uranium, the element used to generate nuclear power, is commonly found in nature. However, nuclear power plants require a large amount of water and there are concerns about safety and radioactive waste. New safety measures are being developed, and if established […]
Kinetic energy is the extra energy an object has when in motion, described as the amount of work required to accelerate it from rest to its current speed. The equation for non-rotating objects is KE = 1/2 * m * v², where KE is directly proportional to speed squared. Kinetic energy can be more complex […]
Renewable energy engineers work in maintenance and development of renewable energy. They need an engineering degree, and some companies require a degree in green or renewable energy. They can work for small or large companies, and pay scales vary greatly. A renewable energy engineer works for an energy company. Some engineers primarily take care of […]
Wind energy is a renewable resource that has been used for thousands of years. It can be harnessed directly or through wind turbines to generate electricity. Wind power is considered clean energy, but building turbines requires resources and can take up valuable land. Despite this, wind power is preferable to polluting and non-renewable power sources […]
Energy is the ability to do work and can be grouped into potential or kinetic categories. Chemical energy is a form of potential energy stored in food, fuel, and batteries. Energy can be converted from one form to another, and during chemical reactions, molecules can be created or destroyed. Respiration converts chemical energy into heat […]
Holistic healing focuses on the body, mind, and soul as a whole, and has roots in ancient Tibetan culture. Holistic healing methods include herbology, acupuncture, and reflexology. While widely accepted in most parts of the world, it is considered alternative medicine in North America. The effectiveness of holistic therapies is still up for debate. Holistic […]
Energy gels are concentrated sports drinks with complex carbohydrates and electrolytes, packaged in single-serving packets for easy consumption during exercise. They provide quick energy and help mitigate lactic acid buildup, but should not be considered a hydrating element. Gatorade is a well-known sports recovery drink. Energy gels are sports drink concentrates that have been thickened […]
Chemical potential energy is stored in atoms and bonds and can be released through reactions. Strong bonds require more energy to break, but release more energy when formed. Examples include burning fuel and the human body using food as fuel. Chemical reactions can be analyzed mathematically. Chemical potential energy is the energy stored in atoms […]
Sustainable energy can be maintained without harming future generations. Renewable energy and energy efficiency are key factors, but environmental impact and independence are also important. Sustainable energy is energy that can potentially be maintained in the future without causing harmful repercussions for future generations. Different types of energy can be considered sustainable and many governments […]
