“The Kinetic energy of an object is energy which is due to its speed.” After achieving this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
The kinetic energy of a non-rotating object of the mass “m” and speed “v” is “1/2 mv ^ 2”. The Kinetic word is actually Origin by a Greek word “Kinesis”, meaning “motion”. Gottfried Leibniz and Johann Bernoulli introduced the first formula of classical mechanics (E ~ mv^2). The terms kinetic energy and work in their present logical implications go back to the mid-nineteenth century. Energy is mainly categorized into two parts: 1) Kinetic Energy & 2) Potential Energy. Furthermore, Kinetic Energy can be exchanged among articles and changed into different sorts of Energy. Hence, Kinetic energy might be best understood by precedents that exhibit how it is changed to and from different types of energy.
First of all, we have to know in traditional mechanics, the Kinetic energy of a point object, or a non-turning inflexible body relies upon the mass of the body just as its speed. The Kinetic energy is equivalent to 1/2 the result of the mass and the square of the speed. In equation structure:
Ek = ½ mv^2
where “m” is the mass and “v” is the speed (or the velocity) of the body. The SI unit of the kinetic energy is JOULE.
How to find Kinetic Energy?
First of all, we have to find the work done
W = F * d
= m * a * d (because F = m x a)
= m x*d * (Vf^2 – Vi^2) / 2d
= ½ * m * Vf^2 – ½ * m * Vi^2
So, Wnet = ΔK
So, This result is known as the work-energy theorem and applies quite generally, even with forces that vary in direction and magnitude. It is important in the study of conservation of energy and conservative forces.
Interesting facts about Kinetic Energy:
Also, A Kinetic energy dependably has a Zero or positive esteem. Similarly, Velocity has positive or negative esteem. Kinetic energy is likewise not a vector. Kinetic energy relies upon the speed of the article squared.
