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 a the motion of the car creates an unbalanced backward force on the balloon be the car moves forward while inertia keeps the balloon in place see the force of inertia on the balloon balances the force from the motion of the car D inertia prevents the force of the car from acting on the balloon

Answer 1

The best explanation for the observation that the balloon appears to move backward when the car starts moving forward is:

**B: the car moves forward while inertia keeps the balloon in place.**

When the car accelerates, the balloon tends to remain in its initial position due to inertia, which is the tendency of an object to resist changes to its state of motion. Thus, even though the car moves forward, the balloon appears to move backward relative to the car.
