For macroscopic objects like baseballs, cars, and airplanes, the uncertainty in position due to a one percent uncertainty in momentum is negligible and practically unmeasurable due to their large mass and size, as described by Heisenberg's uncertainty principle.

For Objects the Size of Baseballs, Cars, and Airplanes, an Uncertainty
