The so-called kinetic energy, in simple terms, refers to the energy that an object has due to movement.
Numerically equal to \(\frac{1}{2}Mv^2\). Kinetic energy is a kind of energy. Its unit under the international unit
system is Joule (J), referred to as coke. 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.
Kinetic energy theorem
Formula: \(Ek = \frac{1}{2} mv^2\)
Quality: \(m = \frac{Ek}{\frac{1}{2} v^2} \)
Speed: \(v^2=\frac{2Ek}{m}\)
