Ayellow ball with a mass of 2 kg is rolling across the floor at 3 m/s. a red ball with a mass of 3 kg is rolling across the same floor at 3 m/s. which ball has greater kinetic energy, and why? the yellow ball has greater kinetic energy, because it is rolling at a higher position above the ground. the red ball has greater kinetic energy, because it has a greater mass. the yellow ball has greater kinetic energy, because it is rolling at a greater speed. the red ball has greater kinetic energy, because it is releasing more thermal energy.

In order to determine which ball has a higher kinetic energy, we first look at the formula of kinetic energy which is:
kinetic energy = 1/2 * mass * velocity²

The factors influencing the kinetic energy of an object are its mass and its velocity. Both of the balls have the same velocity; however, the red ball has a greater mass. Therefore,
The red ball has greater kinetic energy, because it has a greater mass.
We may also determine these quantitatively using the formula given and the kinetic energy of the yellow ball works out to be 9 J and that of the red ball is 13.5 J.
