Question

why does a pendulum moves backward and balloon moves forward when a vehicle starts moving?​

Answer 1

Explanation:

First, the hanging weight swings in the opposite direction as the acceleration and second, it won't stop swinging. The balloon as a large drag force on it compared to its mass that prevents excessive swinging.

Answer 2

Answer:

hope it will help you.........

Explanation:

The key is the acceleration. So, the car is accelerating forward and the balloon also leans forward. ... The air in the car has a higher density in the back of the vehicle than it does in the front. This means that the net force on the balloon due to collisions with the air will be in the forward direction.
