In the physical world, no surface is frictionless. Hence whenever a body moves, the force of friction acts on it. Rest all forces act on the body only when it moves along a curve and not along a straight line.

Understanding Forces Acting on a Body Moving in a Straight Line
When analyzing the forces acting on a body in motion, it is important to consider the nature of the forces involved. Here’s a breakdown of the options provided:
1. Tangential Force
- Tangential force is not necessarily a force that acts on a body moving in a straight line but rather when an object moves along a curved path.
2. Friction Force
- Friction is a resistive force that acts opposite to the direction of motion.
- It can influence a body moving in a straight line by slowing it down or bringing it to a stop.
- This force arises due to the contact between two surfaces, making it essential for motion control.
3. Centrifugal Force
- Centrifugal force is a perceived force that acts outward on a body moving in a circular path.
- It is a result of inertia and does not directly apply to a body moving in a straight line.
4. Centripetal Force
- Centripetal force acts on an object moving in a circular path, directed towards the center of curvature.
- It does not apply to a straight-line motion scenario.
Conclusion
In conclusion, the correct answer is the friction force (option 'B'). This force plays a significant role in the dynamics of bodies moving in straight lines, affecting their speed and direction through resistance. Understanding how friction interacts with motion provides insight into real-world applications, such as vehicle movement and object dynamics.
