Question

if stationary bus suddenly speeds up passengers are thrown in the backward direction give reason​

Answer 1

If a stationary bus suddenly speeds up, passengers are thrown in the backward direction. This is because initially the whole body of a passenger inside the bus was in the state of rest. ... Hence, the passengers are thrown backward when a stationary bus suddenly speeds up.

Answer 2

Answer:

If a stationary bus suddenly speeds up, the passengers are thrown in the backward direction because initially, the passenger’s whole body was in the state of rest inside the bus. However, when the bus suddenly starts speeding up, the lower part of the passenger’s body comes in motion towards the forward direction but the upper part of the body still remains at rest particularly due to the inertia of rest. This is the reason why the passengers are thrown in a backward direction when a stationary bus suddenly increases its speed.
