Why Do You Fall in the Forward Direction When a Moving Bus Brakes to a Stop and Fall Back When It Accelerates From Rest?

By K Balaji|Updated : November 9th, 2022

When the bus brake is applied to stop we move forward and when it accelerates from rest we move back because of the motion of inertia. When bus moves, passenger moves back and when bus stops, passenger moves forward.

Inertia

  1. According to the law of inertia, an object will continue to be in its current state of rest or motion unless another force acts on it.
  2. According to the inertia of motion, a body will resist continuing in uniform motion unless an external force acts on it.

When the bus accelerates from rest:

  • The inertia of the passengers tends to counteract the bus's forward speed when it suddenly starts moving, causing the passengers to slide backward.
  • As a result, whenever the bus accelerates, the passenger prefers to recline.

When you apply the brakes to a moving bus, you get inertia.

  • The bus driver presses the brakes, bringing the vehicle to a stop.
  • On the other side, the passenger makes every effort to keep motion inertia. He receives a push forward as a result.

Types of Inertia

Inertia of Rest

when the body's attempt to maintain its current state of rest in the absence of an outside force is met with resistance.

Inertia of Direction

when the body offers resistance to keep moving in the same direction unless another force acts on it.

Inertia of Motion

When the body offers resistance to remain in a uniform motion until an outside force acts on it.

Summary:-

Why Do You Fall in the Forward Direction When a Moving Bus Brakes to a Stop and Fall Back When It Accelerates From Rest?

Due to the motion of inertia, when the bus brake is applied to stop it, we move forward, and when it accelerates from a halt, we move back. Passengers go backwards when the bus is moving and forward when the bus stops.
