A physics teacher performed a demonstration for a science class by pulling a crate across the floor and measuring the force with a spring scale. While she pulled, a student measured the acceleration of the crate with a handheld electronic device. The results of three trials are shown below. The teacher asked the class to calculate the acceleration of the crate based on the crate’s mass and the force she applied. What conclusion can be made about the difference between the CALCULATED acceleration and the ACTUAL acceleration that occurred in the trials?
