Question

1. people sitting in a moving vehicle experience a push when the vehicle stops. this is due to: gravity acceleration inertia movement

Explanation:

According to Newton's first law of motion, an object in motion tends to stay in motion. When the vehicle stops, the people inside (due to inertia) continue moving forward, creating a "push" sensation. Gravity acts downward, acceleration is a change in velocity (not the direct cause here), and "movement" is too vague. Inertia specifically explains this tendency of objects to resist changes in their state of motion.
