Questions & Step-by-Step Solutions
A speed is measured as 20 m/s with an uncertainty of ±0.5 m/s. What is the absolute error in the speed measurement?
Step 1: Understand what speed is being measured. In this case, the speed is 20 m/s.
Step 2: Identify the uncertainty in the measurement. Here, the uncertainty is ±0.5 m/s.
Step 3: Recognize that the absolute error is the same as the uncertainty in the measurement.
Step 4: Conclude that the absolute error in the speed measurement is ±0.5 m/s.
Absolute Error – The absolute error is the amount of uncertainty in a measurement, represented as the range of possible values around the measured value.
