    One BTU is the amount of energy required to raise one pound of water 1 o F. One gallon of gasoline contains about 125,000 BTU. A related unit is the THERM, or 100,000 BTU. Another familiar unit to physicists is the joule (J), equivalent to 0.239 calories or 9.47 x 10-4 BTU. Most systems of measurement throughout the world use joules to measure ...

  • energy Flashcards | Quizlet

    The amount of gravitational potential energy possessed by an elevated object is equal to the work done against gravity to lift it. The upward force required while moving at constant velocity is equal to the weight, mg, of the object, so the work done in lifting it through a height h is the product mgh.

    Petroleum is the main source of energy for transportation. In 2018, petroleum products accounted for about 92% of the total U.S. transportation sector energy use. Biofuels, such as ethanol and biodiesel, contributed about 5%. Natural gas accounted for about 3%, most of which was used in natural gas pipeline compressors.

  • Energy vs Power - Difference and Comparison | Diffen

    For instance potential energy is dependent on the position of the object, whereas kinetic energy is the energy required to accelerate an object to a particular speed, and so on. Different forms of power could be electric power, which is the rate at which electrical energy is transferred by a circuit, human power, and optical power.

  • Embodied energy - Wikipedia

    Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself. The concept can be useful in determining the effectiveness of energy-producing or energy-saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in ...

  • Changes of Phase, Heat, Temperature | Zona Land Education

    These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.

  • How Force, Power, Torque and Energy Work - HowStuffWorks

    At first glance, you might say that in each case, the car is increasing its speed by 20 mph, and so the energy required for each increase must be the same. But this is not so. We can calculate the kinetic energy required to go from 0 mph to 20 mph by calculating the KE at 20 mph and then subtracting the KE at 0 mph from that number.

  • What Are Energy-Related Organelles? | Sciencing

    Jun 17, 2019 · Organisms in the domain Prokaryota, which includes bacteria and the Archaea (formerly called "archaebacteria"), are almost entirely single-celled, and, with few exceptions, must get all of their energy from glycolysis, a process that occurs in the cell cytoplasm.The many cellular organisms in the Eukaryota domain, however, have cells with inclusions called organelles that carry out a ...
