Newton's 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 impacts due to inertia? Select ALL that apply.

A brake pads on vehicles
B speed bumps installed on the roadways
C guard rails on the interstate along a curve
D lap bars on amusement park rides
E seat belts installed and used in cars.

A, C, D, E.

The apparatus that are installed or used to directly reduce the impacts due to inertia are:

A. Brake pads on vehicles: Brake pads help reduce the speed and stop the motion of vehicles, reducing the impact during a collision.

C. Guard rails on the interstate along a curve: Guard rails are used to prevent vehicles from leaving the road and reduce the impact of collisions.

D. Lap bars on amusement park rides: Lap bars are used to secure passengers in place during the ride, reducing the risk of injury due to inertia.

E. Seat belts installed and used in cars: Seat belts are used to restrain passengers and prevent them from being thrown forward during a collision, reducing the impact forces on the body.
