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 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 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 car moves forward, while inertia keeps the balloon in place.
Inertia prevents the force of the car from acting on the balloon.
The correct statement is:
Inertia prevents the force of the car from acting on the balloon.
The correct statement to explain this observation is: "Inertia prevents the force of the car from acting on the balloon."
When the car starts moving forward, it experiences a forward force. However, due to inertia, the balloon tends to resist changes in its state of motion. Since the balloon was initially at rest inside the car, it has a tendency to stay at rest. As a result, when the car starts moving forward, the balloon appears to move backward relative to the car.
In this case, the observation can be explained by Newton's first law of motion, which states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. The balloon resists the force of the car's motion and maintains its initial state of rest relative to the car.
