      Its what makes spitting straight up in the air a silly thing to do. Gravity is not my science area – as far as I know its one of four fundamental forces. I get lost when people start talking about gravity particles..(gravitons?)

    We were taught that gravity is an acceleration and that to make it a force you have to multiply it by the mass of the object to get the weight which we were taught is a force. This uses Newton’s second law which has the equation f=ma. Does anyone know whether its defiantly defined as a force or acceleration.
