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