Question

check the correctness of the equation E=1/2mv²​

Answer 1

Answer:

K.E=1/2mv^2 or E=mc^2

Explanation:

E means only Energy but K.E. means kienetic energy

Answer 2

Answer:

The equation of the Kinetic-Energy is E = 1/2 mv²

Explanation:

this is the equation of the Kinetic-Energy

E = 1/2 mv²

Energy (E)

unit :- J = kg m² s^(-2)

dimension :- M L² T^(-2)

Mass(m)

unit :- kg

dimension :- M

Velosity(v)

unit :- m s^(-1)

dimension :- L T^(-1)

mv²

unit :- kg [m s^(-1)]² = kg m² s^(-2)

dimension :- M L² T^(-2)

the Dimension of both side in the equation is same

so the equation is correct
