In this lesson, we will learn how to find the uncertainties in the values of quantities that can be calculated from two or more measured values.
Students will be able to
Q1:
An object has a mass of 2ยฑ0.1kg and is moving at a speed of 3ยฑ0.1/ms. What is the uncertainty in the kinetic energy of the object? Start by calculating the uncertainty in ๐ฃ๏จ, and then calculate the uncertainty in 12๐๐ฃ๏จ.
Q2:
In an experiment, a quantity ๐ is found to have a value of 15ยฑ0.3. What is the percent uncertainty in ๐๏จ?
Q3:
In an experiment, a quantity ๐ฅ is found to have a value of 4ยฑ0.1. What is the uncertainty in ๐ฅ๏จ?
