Questions & Step-by-Step Solutions

In an experiment, the mass of an object is measured as 5.0 kg with an uncertainty of ±0.2 kg. What is the absolute error?
  • Step 1: Understand what absolute error means. It is the amount of uncertainty in a measurement.
  • Step 2: Look at the given uncertainty in the measurement, which is ±0.2 kg.
  • Step 3: Recognize that the absolute error is simply the value of the uncertainty.
  • Step 4: Conclude that the absolute error for the mass measurement is ±0.2 kg.
