Do Now: [note: F = ma, where 1 N = 1 kg •m/s²]

Please consider this released STAR test question:

A student attempts to measure the mass of a brick by measuring the force required to accelerate it at 1 m/s² on a level surface. The force required is 2 N, and the student concludes that the brick has a mass of 2 kg. A balance shows that the mass of the brick is really 1.5 kg. The experimental error is most likely due to

A. gravity.
B. work.
C. friction.
D. inertia.
