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 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.

Answer 1

"The car moves forward, while inertia keeps the balloon in place."

Explanation: when the car accelerates forward, the balloon tends to maintain its previous state of motion (inertia), so it lags behind the car and appears to move backward relative to the car.
