Gravity is the force that cause an object with mass pulls everything around it. In 17 centry, scientist Isaac Newton found it by the falling of an apple. This force affects everything and everywhere. For example, the gravity of sun causes the motion of the solar system. We can stand or fall is also an effect of the gravity. Without gravity, we will fly straight to the space and planets, stars will move in lines. For sure we can say gravity is the foremost force in our lives.
