Lesson: Measurement Uncertainty and Resolution High School PhysicsPhysics
In this lesson, we will learn how to define resolution based, and random measurement uncertainties, and show how they effect the values of measurements.
Sample Question Videos
The lengths of the sides of a sheet of paper are measured to be 7.8 cm and 14 cm. Rounding to an appropriate number of significant figures, what is the area of the sheet?
A distance of 115 meters is measured to the nearest meter. The distance is run in a time of 12 seconds, measured to the nearest second. Rounding to an appropriate number of significant figures, what was the average running speed?
The sides of a rectangular tile are measured to the nearest centimeter, and they are found to be 6 cm and 8 cm. Rounding to the same number of significant figures that the side lengths were measured to, what is the area of the tile?
