WebMar 7, 2024 · A two-kilogram mass (something weighing 4.4 pounds on Earth) moving at a speed of one metre per second (slightly more than two miles per hour) has a kinetic energy of one joule. In the centimetre-gram-second system the unit of energy is the erg, 10 −7 joule, equivalent to the kinetic energy of a mosquito in flight.

https://byjus.com/physics/kinetic-energy/
WebIn the International System of Units (SI), the standard unit for kinetic energy is the Joule (J). One Joule is equivalent to 1 kilogram multiplied by metre squared divided by second squared (kg.m²/s²). This unit represents the amount of kinetic energy possessed by an object with a mass of 1 kilogram moving at a velocity of 1 metre per second.

Kinetic energy - Wikipedia
https://en.wikipedia.org/wiki/Kinetic_energy
WebThe kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form: where is the mass and is the speed (magnitude of the velocity) of the body. In SI units, mass is measured in kilograms, speed in metres per second, and the resulting kinetic energy is in joules .
