In Newtonian physics, the kinetic energy ENewtonian of a body with mass m moving with velocity v is given by the equation
ENewtonian = (1/2)mv2.
In special relativity, the relationship is instead given by
Erelativistic = mc2 / (1 - (v/c)2)1/2,
where m now denotes the rest mass of the particle and c is the speed of light. Note that this diverges as vapproaches c, so that it takes an infinite amount of work to accelerate a body of non-zero rest mass to the speed of light.
Since v < c, the relativistic formula can be expanded in a power series like so:
Erelativistic = mc2 (1 + (1/2)(v/c)2 + ...),
where the ellipsis "..." denotes terms of order (v/c)4 and smaller. If the velocity is small compared to the speed of light the higher order terms may be neglected, giving
Erelativistic = mc2 + (1/2)mv2,
which is just mc2 + ENewtonian. The term mc2 is sometimes called the rest energy of the body, being the (relativistic) kinetic energy of the particle when v = 0.
In some relativity textbooks, the "relativistic mass" of the body is sometimes defined as Erelativistic / c2, giving a "mass" which increases with velocity (becoming infinite as v approaches c).
kinetic energy is the energy that a particle has obtained due to its motion.It mainly depends upon the mass of the body and its velocity.
kinetic energy is mathematically calculated as (0.5 x mass of the body x square of its velocity)
The Total "kinetic" energy of a particle is the same as the total Potential energy. Kinetic energy is the same as the potential energy, both are scaler energy or Potenttial energy = vh/r = vp= mv2.
The real Particle "motion" energy is vector energy cmV = cP, the Momentum energy. The Total Particle energy is Quaternion energy W = -vh/r + cmV = -vh/r + cP = [-vh/r, cP].
Work = change in Kinetic Energy Because friction acts in the opposite direction of the motion of an object, kinetic energy must be decreased in order to maintain the above equation. Friction opposes motion. Friction converts the kinetic energy of a particle into heat and sound.
Kinetic energy of particles is the energy associated with their motion. It is given by the formula KE = 1/2 mv^2, where m is the mass of the particle and v is its velocity. The greater the mass or velocity of a particle, the greater its kinetic energy.
The sum of all kinetic energy in a system is equal to the total kinetic energy of all the individual particles in the system. It is calculated as the sum of ( \frac{1}{2}mv^2 ) for each particle, where ( m ) is the mass of the particle and ( v ) is its velocity.
Particles in motion will generally have kinetic energy, or momentum. Cumulative effects of motions of groups of particles (Brownian motion) is perceived as heat. According to the duality of matter (wave-particle), a moving particle can also be said to have a wavelength (De Broglie wavelength) associated with its mass and momentum.
No, thermal energy refers to the total kinetic energy of particles in a substance, while internal energy includes both kinetic and potential energy of the particles within a system. Thermal energy is a component of internal energy, but internal energy also includes other forms of energy such as potential energy due to particle interactions.
Average
Kinetic energy
The higher the speed the more the kinetic energy.
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
Thermal Energy
Kinetic energy is due to the motion of the particles .it is the energy processed by the virtue of the motion of the particle .
mechanical energy
kinetic energy is the energy that a particle has obtained due to its motion.It mainly depends upon the mass of the body and its velocity. kinetic energy is mathematically calculated as (0.5 x mass of the body x square of its velocity)
temperature
Kinetic
temperature is the average kinetic energy of a particle
If something is made to move quickly, it gets kinetic energy.
