Answer:
Distance = 50m
Displacement = 50m to the right
Explanation:
Distance is the total length of a given path. It is a scalar quantity and thus takes no consideration on the direction of the path.
Displacement on the other hand is the change in position of an object. It is a vector quantity and takes consideration on the direction of the object.
From the question:
The swimmer swims half lap by moving from the left end to the right end of a pool that is 50m long.
Distance = total length of the given path = 50m
Displacement = change in position of the swimmer from the left end (0m) to the right end (50m) = 50 – 0 = 50m
Since direction is important in displacement, the complete details of the displacement should be 50m to the right
Answer:
The distance is 50m and the displacement is also 50 m
Explanation:
the swimmer traveled 50m =distance
the swimmer was now 50m away from the start=displacement
