Explanation:
According to the Law of Gravitation, something going down has more kinetic energy than something going up because it attracts pressure from around it when going down. When it goes up, it has less gravitational force and inertia also stops the ball from rolling upward. Therefore, without the amount of kinetic energy, it will not have the same amount of acceleration.
<span>This would be an isotropic object. Having isotropy means that, in every direction that the object could be measured, a similar (or the same) value or measure would be reached. This allows an object to be easier to shape and makes it easier to understand and predict the object's behavior under different circumstances.</span>
