How should engineers design a car's crumple zone to reduce impact force during a crash?

Design it to collapse and extend impact time.

Why is there no data loss when light travels through fiber-optic cables?

Light experiences total internal reflection.

What is the scientific reason for replacing old light bulbs with LEDs to save energy?

LEDs convert more electricity into light.

What is the rotational counterpart to linear mass (inertia)?

Moment of inertia

Which symbol represents the angular equivalent to linear displacement?

$\theta$ (Theta)

If an object is moving in a perfect circle at a constant speed, what happens to its linear velocity vector?

It continuously changes direction.

Which rotational quantity is paired with the linear quantity of force?

Torque

A child sits on a spinning carousel. If the child moves to a seat twice as far from the center, how does their linear speed change?

It doubles.
