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
Remember, a force is either a push or pull. The 6 are: normal force; applied force; frictional force; tension force; spring force; resisting force; Let's investigate how these forces can be seen in our lives. Normal Force. A book resting on a table has the force of gravity pulling it toward the Earth. But the book is not moving or accelerating, so there must be opposing forces acting on the book. This force is caused by the table and is known as the normal force.
