Balanced forces. When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces. If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a stationary object stays still a moving object continues to move at the same speed and in the same direction
1 force: a push or a pull; can be measured by the amount of acceleration it can give a mass. 2  weight: downward pull of gravity on an object. 3  normal force: upward force of the ground, perpendicular to the surface.  balanced forces: forces acting on an object that cancel each other.
