Question 6. A passenger sitting in a bus moving at uniform speed, feels pushed backward whenever the bus is accelerated forward. This type of force is called (a) Gravitational force (b) real force (c) fictitious force or pseudo force (d) frictional force
A person standing in a bus falls backwards when bus suddenly starts moving in forward direction. This happens because when bus starts moving forward, lower part of the person begin to move with the bus whereas the upper part of the body tends to remain in rest due to inertia.
