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)
• Inertia prevents the force of the car from acting on the balloon.
• The motion of the car creates an unbalanced backward force on the balloon.
• The force of inertia on the balloon balances the force from the motion of the car.
• The car moves forward, while inertia keeps the balloon in place.
