THE COMBINED EFFECT OF VARIOUS FORCES:THE COMPOSITION OF FORCES
The great variety of situations which life presents, suggests that bodies interact with more than one object at the same time.  This means that the number of forces acting on it are not normally limited to one.

We hold an object on a table using the action of two springs.

1- Observe the visual as it first appears and try to describe the forces acting on the object.  What will happen if we release the object from the action of the springs?  You can find out by releasing the object with the "play" control in the visual.

2- Click on home and move the object to the point on the plane (0, 1.5). Observe the forces that act in this new situation.

Learn

The action of more than one force on an object produces just one effect.  In the case above it produces one single movement.

Question

Do you think that by using just one spring in the visual above we could produce the same effect as that due to the combined action of the two forces?
