The lecture Scientific Notation Example and Unit Analysis by Jared Rovny is from the course Methods and Common Calculations. It contains the following chapters:
Which of the following is a correct way to rewrite 65,000,000×15,000/2,300?
To calculate force (F) we have to multiply mass times acceleration. What is another way to write this? Note that brackets around a variable mean “units of” that variable, where we have [x]=meters, [m]=kilograms, [t]=seconds, [v]=meters/second, [a]=meters/second2.
If a quantity called “Force” has units of (kilograms∙meters/second2), which of the following could be a valid equation for the Force squared, F2? Note that brackets around a variable mean “units of” that variable, where we have [x]=meters, [m]=kilograms, [t]=seconds, [v]=meters/second, [a]=meters/second2.
What is another way to write (2.5×1.8/2.7)×10^6?
What is the another way to write 3,200×5,000,000/2.500,000,000 in scientific notation?
Complete the equation x=x0+v0t+?
Calculating acceleration involves dividing velocity by time. How do you represent this in terms of unit?
