What is the formula for calculating kinetic energy? ke = mv2 ke = 2mv2 ke = m2v ke = 2m2v

Kinetic energy is the energy possessed by an object having some mass and moving at some speed due to its motion. Kinetic energy is given as

KE = (0.5) m v²

where KE = kinetic energy

m = mass of the object in motion

v = speed of the object in motion.

it is a scalar quantity and has only magnitude and no direction.

Explanation :

An object is moving with initial velocity of u and its final velocity is v. If it covers a distance s moving with an acceleration a. So, the relation between them is :

So, ...............(1)

If a force (F = m a) is applied to it then the work is done by it. It is given as :

If u = 0

then,

From work energy theorem, the work done is equal to the change in kinetic energy.

The kinetic energy is possessed due to the motion of an object.

Hence, this is the required solution.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
