Definitions:

Body Roll

The tendency of a vehicle's body to lean to one side during cornering, affecting stability and handling.

Compress Spring

The act of applying force to a spring to decrease its length temporarily, storing potential energy that can be released when the force is removed.

Unsprung Weight

Vehicle weight that is suspended beneath the springs and therefore is not carried by the springs. Examples include the weight of the wheels and tires, brake components, control arms, steering knuckles, and some rear axles.

Steering Knuckle

A part of the vehicle's steering and suspension system that connects the wheel hub to the suspension components, allowing for wheel rotation and steering.
