Gravity

Explain to me why gravitity gives objects a negative accleration?

Well, we talked about this yesterday pretty much the whole class. It gives it a negative acceleration because it pulls objects down to earth. When things fall such as a pencil it gets a negative acceleration.

It is a negative acceleration because it is falling down. On a grid downward is always negative and that is why gravity has a negative acceleration. If it was not negative, the formulas would not work.

Gravity gives objects negative accleration because it is falling down. A downward motion means negative. For example, on graph paper the line under zero would be negative because it is going downward.

It is becase it is moving down. Like Pete said on like a gragh moving down or to the left is negative. It would then only make sense that it is the same in physics.
