A compressed spring is pushing a block across a rough horizontal table. How many force vectors would be shown on a free-body diagram? Name them.
The upward normal force, left kinetic frication, right spring force, and downward gravity are depicted in the free body diagram.
Given : A compressed spring is pushing a block across a rough horizontal table.
If we have an object that is being acted upon by forces, we must be able to detect those forces. The technique for recognizing forces will be depicted in visual form, as seen in the picture below.
The following steps are taken to determine the forces:
1. We recognize the item, which is a block that is speeding up due to the spring's force.
2. We draw the block's image as indicated in the diagram below:
3. We draw a closed circle or a curve around the object, as indicated in the figure below by the dashed curve.
4. We name and label the object's contact forces, which in this case are the normal force, the spring force, and the ground's kinetic friction.
5. We name the long-range forces, which are merely gravity in this case.
As a result, we can determine the forces acting on the block using the diagram, where the forces are the normal force , which acts upward, the kinetic frication , which acts in the opposite direction of the plane's motion, the spring force , which acts in the same direction as the motion, and the gravitational force or the block's weight, which acts downward due to the block's weight.
