Gravity is a force that acts upon a ball after it is thrown?
Elena-2011 [213]

True or false, depending on the specifics. True, because the gravity makes it go to the ground. False, because gravity is always working, so you don't need to throw the ball. However since it doesn't say that it only happens when you throw it. The answer should be true.
