Question

multiple choice question
aristotle thought that a thrown object was pushed by the air circulating back to fill the void left by the object and this was the force to keep the object in motion. in a moving car the air is still, but if the driver steps on the brakes loose objects like groceries and books will start to move towards the front of the car. which answer explains why.
○ applying the brakes cause a change in the air pressure in the car.
○ the objects were already in motion with the moving car.
○ the force of the car seats pushes the objects forward.

Explanation:

When a car is moving, loose objects inside are also in motion at the car's speed. When brakes are applied, the car slows, but the objects continue moving forward due to inertia (they maintain their state of motion until acted on by an external force).

Answer:

The objects were already in motion with the moving car.
