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)

Answer 1

This observation can be explained by the principle of relative motion. When the car starts moving forward, the air inside the car also starts moving with the car. However, the balloon is not directly attached to the car and is free to move independently. As a result, the balloon continues to move in its original direction until it is acted upon by an external force, such as air resistance or friction. This creates the illusion that the balloon is moving backward relative to the car, even though it is actually moving forward with the air inside the car.
