if you’re in a car moving at a high speed, and you stop abruptly, how would what happens be different with wearing a seatbelt as opposed to not wearing a seat belt? which of newton’s 3 laws would apply?

If the car were to abruptly stop and the seat belts were not being worn, then the passengers in motion would continue in motion. Assuming a negligible amount of friction between the passengers and the seats, the passengers would likely be propelled from the car and be hurled into the air. Once they leave the car, the passengers becomes projectiles and continue in projectile-like motion.

Hope this is helpful!!! :)

the independent variable, or the one that is intentionally manipulated is the speed.

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid
