D) the object moves slowly or not at all.
E) the object absorbs all the energy of the measuring device.

Question

Quizplus · Accepted Answer

If the energy of the probe (measuring device) is much smaller than the energy of the object being measured, then the probe will not have a significant effect on the object. Therefore, measurements can be made on a macroscopic object without altering the object.
