When a passenger on a bus traveling at a constant speed is pushed backward, the bus accelerates forward due to an external force. This force is referred to as a fictitious or pseudo force.
Fictitious or pseudo forces are forces that appear to act on objects in non-inertial frames of reference, such as accelerating or rotating frames. In this case, when the passenger is pushed backward, their inertia tends to keep them at rest or in uniform motion. However, because the bus is accelerating forward, a fictitious force is experienced by the passenger, pushing them backward.
This force is not a real force in the sense that it does not arise from a physical interaction between objects. It is a result of the frame of reference being non-inertial, and it is necessary to explain the observed motion within that frame.

Understanding Pseudo Forces
When a passenger is pushed backward on a bus that is moving at a constant speed, it may feel like there is a force acting on them, even though the bus is not accelerating. This sensation is explained by the concept of fictitious or pseudo forces.
What is a Pseudo Force?
- A pseudo force, also known as a fictitious force, arises in a non-inertial reference frame.
- In this case, the bus is the non-inertial frame because it is accelerating forward while the passenger feels pushed backward.
Why Does the Passenger Feel Pushed Backward?
- When the bus accelerates forward, the inertia of the passenger causes them to resist this change in motion.
- This resistance makes it seem as if a force is acting in the opposite direction (backward), which is not due to any physical interaction but rather the passenger's reluctance to accelerate with the bus.
Real vs. Pseudo Forces
- Real forces, like gravitational or frictional forces, arise from interactions between objects.
- Pseudo forces do not stem from physical interactions but instead are perceived due to the observer’s frame of reference changing.
Conclusion
Understanding that the force perceived by the passenger is a pseudo force helps to clarify the principles of motion and reference frames. It demonstrates how motion can be perceived differently based on the observer's position, which is crucial for concepts in physics and everyday experiences.
