Friction always acts in the opposite direction to the motion of an object, which means it will slow down the object. This resistance is due to the interactions between the surfaces in contact. For example, a box sliding on a rough surface will come to a stop quicker than on a smooth surface due to greater friction.

Understanding Friction and Motion
Friction is a fundamental force that plays a crucial role in the motion of objects. It is the resistance that one surface or object encounters when moving over another. Here’s how friction affects motion:
Friction Always Opposes Motion
- Friction acts in the opposite direction to the motion of an object.
- This opposition results in a reduction of the object's speed, ultimately slowing it down.
Examples of Friction in Action
- Sliding Objects: When a book slides across a table, friction between the book and the table causes it to eventually come to a stop.
- Walking: When you walk, friction between your shoes and the ground allows you to push off without slipping. However, without sufficient friction, you would slide instead of walking.
Types of Friction
- Static Friction: Prevents an object from starting to move. It must be overcome to get an object moving.
- Kinetic Friction: Acts on moving objects and is generally less than static friction. It slows down moving objects.
Impact on Everyday Life
- Friction is essential for many daily activities, such as driving a car or writing with a pencil.
- While it is necessary for movement, excessive friction can lead to problems like wear and tear on machines.
Conclusion
In summary, option 'A' is correct because friction always acts to slow down an object's motion. Understanding friction is key to comprehending how forces interact and influence movement in our daily lives.
