1) Amy runs 2 miles south, then takes a turn and runs 3 miles north the displacement is 1 mile North.
2) Distance is 800m and Displacement will be zero.
3) Distance is 90 feet, and Displacement is 30 feet.
4) Distance is 4 miles and Displacement is 0.
Displacement is the measurement of "how far an object is out of place," whereas distance refers to "how much ground an object has covered during its motion."
The spacing between two specified points is represented by the one-dimensional quantity of displacement (symbolized as d or s), commonly known as length or distance. The meter serves as the standard displacement unit in the International System of Units (SI) (m). Usually, displacement is defined or measured along a straight line.
1) Here, the person goes 2 miles south and then 3 miles north.
3-2 = 1 mile north
So, Displacement is 1 mile North.
2) It is given that Jermaine runs 2 laps around the track.
The perimeter of the track on which he runs = 400m
Here as it is given laps, which means the track is circular in shape.
Distance covered in 1 lap
So total distance covered in 2 laps= 2 × 400 = 800 m
Displacement will be zero as the initial and the final position is the same. So, no positional change happens.
