What is the kinetic energy of a body of mass 1 kg moving with a speed of 2 m/s?

उत्तर
We have to find the kinetic energy of the moving body. We have,
Mass of the body (m) = 1 kg
Speed of the moving body (v) = 2 m/s
So,
`K.E = 1/2 mv^2`
Where,
K.E - Kinetic Energy
m - Mass
v - Speed
Therefore,
`K.E = 1/2 (1) (2)^2 "J"`
= 2 J
So , the kinetic energy of the moving object is 2 J .
