Question

the kinetic energy possessed by a body depends upon its mass and speed . find the expression for kinetic energy of body using the method of dimensions ​

Answer 1

Answer:

K. E=[ML^2T^-2]

Explanation:

K.E=1/2mv^2

mass=[M], velocity =[LT^-1]

K.E=[M][LT^-1]^2

K.E=[ML^2T^-2]

Answer 2

Answer:

mass

Explanation:

Kinetic energy of the body K= 1/2mv square

⟹ K∝m and K∝v square

Thus, kinetic energy of a body depends on the mass of the body as well as its velocity.
