We can compare the two by their kinetic energies. The kinetic energy is the energy when an object
is in motion. It is expressed as the product of the mass of the object and the
square of the velocity divided by two. We assume a velocity of 1 m/s for this problem.
KE = mv^2/2
KE1 = 10 (1)^2
KE1 = 10 J
KE2 = 1(1)^2
KE2 = 1 J
Therefore, compared to the 10 kg ball, the 1 kg ball has lesser kinetic energy.
