Question
In the following figure, the ball hanging from the roof of the bus moves towards the left if the bus suddenly moves towards the right (direction shown b arrow)?
This is due to ___
- Inertia
- Speed
- State of rest
- State of motion
Hint:
Inertia
The correct answer is: Inertia
Since the system was initially at rest, the inertia of the ball is that of rest. When the car suddenly moves towards the left the inertia of the car changes but not that of the ball.
