Question

You travel in a car 30 miles north to ava and home again. what is your distance? __________________________________________ what is your displacement

Answer 1

If you travel 30 miles somewhere and then come home again your distance is 60 miles.  Your displacement is 0 because it is the ending position minus the beginning position, which are the same place (home).  In other words, displacement is a vector and distance is a scalar.
