Kinetic energy theorem online calculator (quality speed)



The so-called kinetic energy, in simple terms, refers to the energy that an object has due to movement. Kinetic energy is a kind of energy, and its unit under the International System of Units is Joule (J). It should be noted that kinetic energy (and the various functions corresponding to it) are scalar, that is, only the size and no direction. When summing, only the algebraic sum is calculated, and the parallelogram rule of vector (mathematical called vector) addition is not satisfied.   The kinetic energy theorem does work: \(W_ T=1/2(m v_ f^2)-1/2m v _i^2\)   In the formula:   WT = total work; m = mass; vi = initial velocity; vf = final velocity.
