"Rotational mass"
Mass--regular, ordinary, linear mass--is a measure of inertia, of how easy or difficult it is to put an object in motion or to bring it to rest.
*lighter wheels/tires will result in faster acceleration and deceleration
"sprung and unsprung weight"
In simple terms, a vehicle’s sprung weight is supported by springs of one kind of or another (coiled springs, air springs, Belleville springs). Unsprung weight moves up and down with the wheels as they travel over bumps, potholes, and other obstructions. So unsprung weight includes the wheels, tires, brake assemblies, differential, solid drive axles, hub motors, and anything directly connected to the wheels is unsprung mass. This still leaves the majority of the vehicle’s components weight as sprung weight—the chassis, motor, transmission, body, and interior, as well as the passengers and cargo.
