Question

10 multiple choice 1 point you are the driver in a car at rest. the passenger takes a sip of water and you slam on the accelerator. the water splashes in your friends face. what is the cause of this? inertia pushed the water into your friends face. when the car accelerated the water became weightless momentarily because of the waters inertia. everything is accelerating around the water. the water has inertia and has the tendency to stay at rest. your friends face accelerated into the water. the inertia of the car accelerated the water into your friends face because the car has more inertia than the water.

Explanation:

Inertia is the tendency of an object to resist changes in its state of motion. When the car accelerates, the water in the passenger's cup wants to stay at rest due to inertia. As the car and the passenger (including the face) accelerate forward, the water appears to splash forward relative to the accelerating frame of the car. The water itself doesn't get "pushed" by inertia in the sense of a force, and it doesn't become weightless. The car's inertia doesn't directly accelerate the water into the face in the way described. The correct idea is that the water resists the change in motion and the accelerating face moves into the water.

Answer:

Everything is accelerating around the water. The water has inertia and has the tendency to stay at rest. Your friend's face accelerated into the water.
