Time it takes a ball to roll down a slope. Gravity.

The value of gravity on the moon is one sixth what it is on earth. If a ball was rolled down a slope would it take the ball more, less, or equal time to roll to the bottom as compared to on earth?

Acceleration on an inclined plane $\displaystyle = g \sin $ $\displaystyle \theta$

The ball would take more time to roll down the slope on the Moon than on Earth, because of a lower value of acceleration.

I hope that helps.
