Multiple Choice

If a ball is sitting on my desk and an unbalanced for is applied, what will happen?

• The ball will stay sitting on the desk.

• The ball will roll and then float.

• The ball will roll and then fall due to friction and then stop once it hits the floor because forces are balanced.
