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 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 best explanation for the observation of the balloon moving backward relative to the car when the car starts moving forward is:

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

This statement accurately describes the effect of inertia, which is the property of an object to resist changes to its state of motion. When the car accelerates, the balloon tends to remain in its original position due to inertia, making it look like it is moving backward relative to the car.
