Why do the drive wheels turn in the opposite direction when a car is jacked up?

The drive wheels turn in the opposite direction when a car is jacked up because of the way the differential works. The differential is a device that allows the wheels on an axle to turn at different speeds, which is necessary when going around corners. When a car is jacked up and one of the drive wheels is turned, the differential causes the other drive wheel to turn in the opposite direction. This is because the differential is designed to transmit power to both wheels equally, but in opposite directions.
