Question

As a bus accelerates, the passengers on the bus are jolted toward the back of bus. Explain what causes the passengers to be apparently pushed backward.

Answer 1

Inertia. According to the newton's First law any object in motion will continue to move with the same velocity unless a force acts upon it. when bus accelerates the passengers according to the first law still are moving with the original speed that creates jolting toward the back.
