Question

if you were in a car crash and werent wearing your seat belt, youd keep moving at the speed of the crash.

true

false

Explanation:

Analyze the physical scenario

This question relates to Vehicle Safety and the physical laws governing motion during a collision. According to Newton's first law of motion (inertia), an object in motion stays in motion at a constant speed and direction unless acted upon by an external force.

Apply inertia to a car crash

When a vehicle is traveling at a certain speed, the occupants inside are also moving at that same speed. If the vehicle suddenly stops due to a crash, an external force stops the car. However, if an occupant is not wearing a seat belt, there is no restraining force acting directly on them to slow them down immediately.

Determine the occupant's motion

Without a seat belt to secure them to the vehicle, the occupant will continue moving forward at the vehicle's pre-crash speed until they strike an object inside the car (like the steering wheel, windshield, or dashboard) or are ejected from the vehicle. Therefore, the statement is true.

Answer:

• TRUE (Correct answer)
• FALSE
