Question
Which force is acting here when the object shown below is not moving?
- Static friction
- Sliding friction
- Rolling friction
- Fluid friction
Hint:
If an object is not moving on the application of an external force, it means the object has a static frictional force that resists the object from motion.
The correct answer is: Static friction
When the object as shown below is not moving, static frictional force is acting here.
- The static force holds an object from moving even when an external force is applied.
- The static force adjusts itself against the motion of the applied force.
- The object subjected to the static force won't move and it should be removed in order to move the object.
