Question

1. newtons law of inertia describes how an object in motion will stay in motion unless acted upon by an outside force. the concept of inertia is responsible for injuries during collisions. which of these apparatus is installed or used to directly reduce the impact due to inertia? select all that apply. a brake pads on vehicles b lap bars on amusement park rides c seat belts installed and used in cars d speed bumps installed on the roadways e guard rail on the interstate along a curve

Explanation:

Newton's first law (law of inertia) states that an object in motion stays in motion unless acted upon by an external force. Seat belts (C) prevent passengers from continuing to move forward (due to inertia) during a sudden stop (like a collision). Brake pads (A) work by applying a force to stop the vehicle's motion (countering its inertia). Guard rails (E) along a curve on the interstate prevent vehicles from continuing in a straight - line motion (due to inertia) and veering off the road. Speed bumps (D) are not directly related to countering inertia in the context of collisions. Loops on amusement park rides (B) are more related to centripetal force and the experience of weightlessness rather than countering inertia to prevent injury from the law of inertia.

Answer:

A. brake pads on vehicles, C. seat belts installed and used in cars, E. guard rail on the interstate along a curve
