Question

28) Q: A: You are sitting in a car that isn't moving; suddenly, the car quickly accelerates. Your body seems to be pushed back against the seat. Which word best explains why your body seemed to be pushed backward against the seat?

Answer 1

the seat is moving with the car and pushing you to keep up with the car or else the seat breaks and you go flying backwards until something stops you .... ouch.

You feel pushed back against the seat, but it's the seat pushing you forward.

Answer 2

Inertia.

Step-by-step explanation:

The first law of Newton states that a body will remain in the same state of motion ( relative rest or uniform movement) if there is no force applied to it.

Why will the body remain in the same state of motion? This is because of inertia.

Inertia is the property of bodies that tries to keep them in a state of motion.

In the case that the car suddenly moves, your inertia tries to keep you in a relative rest to the ground, that's why your body feels like being pushed back.
