Sarah walks part way around a swimming pool She walks 50 yards north then 20 yards east and 50 yards south. The magnitude of her total displacement during the walk is 20 yards.
The displacement of an object is its Volume.
Average Velocity
No. Distance is never negative, and total distance travelled doesn't decrease during a trip. The distance from A to B is the same as the distance from B to A. Displacement, on the other hand, can be negative, and can decrease during a trip. The displacement from A to B is the same magnitude, but opposite sign, as the displacement from B to A. An example would be if you went from your home to a friend's house 1 mile to the east. After you reach your friend's house, you have travelled a distance of 1 mile and your displacement from your starting position is 1 mile. When you come back home from your friends house, you travel a distance of 1 more mile. Your total distance travelled is now 2 miles, but your displacement from your starting location is zero (because you are back where you started.) Distance does not have direction, and is always positive (or zero). Displacement has direction, and can be negative, positive, or zero.
Work = (force on an object) times (displacement of the object during the time the force is applied to it).
A displacement pile is one which displaces soils during installation. For instance a driven pile displaces the soil as it is being driven into the ground. A non-displacement pile is one formed by some other method, perhaps a drilled shaft, or some other installation method.

The displacement of an object is its Volume.
80
The total is 3
3
Average Velocity
The answer is 80 because 100-30+10 is 80.

The magnitude of an earthquake is caluated to measure the amount of energy released during the earthquake.
