A fast-moving object has more kinetic energy compared to a slow-moving object of the same mass because kinetic energy is directly proportional to the square of the object’s velocity. This means that even a small increase in velocity results in ...
Work is the transfer of energy from one object to another or the conversion of energy from one form to another. In the examples, the cricket ball does work on the wicket by transferring its kinetic energy to it. Similarly, ...
When the hammer is raised, it has gravitational potential energy due to its height above the nail. As the hammer falls, this potential energy is converted into kinetic energy. When the hammer strikes the nail, the kinetic energy is transferred ...
An object raised to a certain height possesses gravitational potential energy. This energy is given by the formula: PE = mgh where m is the mass of the object, g is the acceleration due to gravity, and ℎ is the height above ...
Kinetic energy is the energy possessed by an object due to its motion. It is given by the formula: KE= 1/2mv² where m is the mass of the object and v is its velocity. In the example of the cricket ...
Tidal energy is harnessed by capturing the energy from the rise and fall of sea levels caused by the gravitational forces of the moon and the sun. This energy can be converted into electricity using tidal turbines or tidal barrages. ...
Biofuels are renewable energy sources derived from organic materials, such as plant biomass or animal waste. The primary sources of biofuels include crops like corn, sugarcane, and soybeans, which can be processed into bioethanol and biodiesel. Biofuels can be used ...
Nuclear power plants generate energy through the process of nuclear fission. In fission, the nucleus of a heavy atom, such as uranium-235 or plutonium-239, is split into two smaller nuclei, along with a few neutrons and a large amount of ...
Geothermal energy is the heat derived from the Earth’s interior. This energy can be harnessed by tapping into underground reservoirs of hot water and steam, which can then be used to drive turbines connected to electricity generators. Common methods of ...
