Question

Frictional force always acts in which direction

• A. opposite to that of the object in motion
• B. in the same direction as that of the object in motion
• C. in any direction
• D. none of the above

Answer 1

The correct option is A

opposite to that of the object in motion

Frictional Force

1. Frictional Force refers to the force generated by two surfaces that contact and slide against each other. And will reduce the speed of motion of an object
2. This is a force that resists the relative motion or tendency to such motion.
3. The frictional force is directly proportional to the roughness of the surface. The frictional force will be more for a rough surface and it will be less for smooth surfaces.
4. Intermolecular interactions between the bodies create frictional forces.
5. Friction offers resistance.
6. The frictional force acts opposite to that of the object in motion

Hence, option A is the correct answer.
