Question

20).(a.) Why do you fall in the backward direction when a bus accelerates ​

Answer 1

Answer:

As the driver applies brakes, the bus comes to rest. But, the passenger tries to maintain the inertia of motion. As a result, a forward force is exerted on him. Similarly, the passenger tends to fall back when the bus accelerates from rest because when the bus accelerates, the inertia of the rest of the passenger tends to oppose the forward motion of the bus. Hence, the passenger tends to fall back when the bus accelerates forward.
