But they can be added together to give the resultant force. This is a single force that has the same effect on the object as all the individual forces acting together. For example a rocket travelling into space with a thrust of 1000N and a weight of 200N will begin to accelerate because the resultant force is 800N. When all forces are balanced, the resultant force is zero. In this case: A stationary object remains stationary and a moving object keeps on moving at the same speed and in the same direction. For example, in a tug-of-war competition, the resultant force when in a stalemate is zero, because both teams are pulling on the rope with equal force. In this case the result is stationary. However, when a skydiver jumps out of a plane, his weight is greater than the air resistance at first and he starts to accelerate. He then reaches a point where his weight and air resistance balance out, this is called terminal velocity and the resultant force is zero, but don't worry, he's not stationary of course, he's just plummeting to the ground at a constant speed that's all.\n
