TRUE OR FALSE Measurement of the position and velocity of a particle cannot be measured simultaneously with the same precision and accuracy.

True.

Explanation:

To describe the problem of trying to locate a subatomic particle that behaves  like a wave, Werner Heisenberg formulated what is now known as the Heisenberg  uncertainty principle: it is impossible to know simultaneously both the momentum p  (defined as mass times velocity) and the position of a particle with certainty.

Making measurement of the momentum of a particle more precise means that the position must become correspondingly less  precise. Similarly, if the position of the particle is known  more precisely, its momentum measurement must become less precise.
