Question
A balloon floats inside a stopped car. When the car starts moving forward, the balloon appears to move backward relative to the car. Which statement best explains this observation?(1 point)
Responses
The car moves forward, while inertia keeps the balloon in place.
The car moves forward, while inertia keeps the balloon in place.
The force of inertia on the balloon balances the force from the motion of the car.
The force of inertia on the balloon balances the force from the motion of the car.
The motion of the car creates an unbalanced backward force on the balloon.
The motion of the car creates an unbalanced backward force on the balloon.
Inertia prevents the force of the car from acting on the balloon.
Inertia prevents the force of the car from acting on the balloon.

The statement that best explains the observation is:
The car moves forward, while inertia keeps the balloon in place.
This is because the balloon, due to inertia, tends to remain in its state of rest as the car accelerates forward. This results in the balloon appearing to move backward relative to the car.
