I need help with this question "A swimmer swims an entire lap, moving from the left end to the right end and back again to the left end in a pool that is 50 meters long". what is the Distance and Displacement?
distance = 2*50 = 100 m
Since he ends where he started, the displacement is zero m.
Looks like you need to review this topic a bit more.
Well, let me jump right into this! The distance traveled by the swimmer is, of course, 100 meters. Since they move from the left end to the right end and then back again to the left end, they cover a total distance of 50 meters + 50 meters = 100 meters, just like me trying to find a parking spot at a crowded circus.
Now, when it comes to displacement, it's a little trickier. Displacement is all about measuring the straight-line distance from the starting point to the ending point. In this case, since the swimmer ends up back at the left end, their displacement is... you guessed it... ZERO! It's just like the feeling you get when you realize you left your clown shoes at home and have to walk around barefoot at the circus - a big ol' zero in terms of displacement.
So there you have it, a distance of 100 meters and a displacement of zero. Keep swimming, my friend, and don't forget to bring your sense of humor with you!
To find the distance and displacement of the swimmer, we first need to understand the difference between the two terms:
- Distance refers to the total length covered by an object, irrespective of the direction. It only takes into account the magnitude of the movement.
- Displacement is a vector quantity that refers to the change in position of an object in a specific direction. It takes into account both the magnitude and direction of the movement.
In this case, the swimmer swims from the left end to the right end and then back to the left end in the pool that is 50 meters long.
The distance covered by the swimmer is the total path length, which is the sum of the distance from left to right and back to the left end. This can be calculated as:
Distance = (distance from left to right) + (distance from right to left)
Distance = 50 + 50
Distance = 100 meters
So, the distance covered by the swimmer is 100 meters.
The displacement of the swimmer, on the other hand, refers to the overall change in position. Since the swimmer starts and ends at the same location, the displacement is zero.
Therefore, the displacement of the swimmer is 0 meters.
To find the distance and displacement of the swimmer, we need to understand the difference between the two concepts:
Distance is the total length covered by an object irrespective of its starting point and direction. It is a scalar quantity and is always positive.
Displacement is the straight-line distance between the starting and ending points of an object's motion. It takes into account the direction and is a vector quantity, meaning it includes both magnitude and direction.
In this case, the swimmer starts from the left end, moves to the right end, and then returns to the left end. Therefore, the swimmer covers a distance of 50 meters from the left end to the right end and an additional 50 meters on the return journey, resulting in a total distance of 100 meters (50 + 50).
Since the swimmer ends up at the same position where they started, their displacement is zero. Displacement is calculated by finding the difference between the initial and final positions, considering both magnitude and direction. In this case, the swimmer's initial and final positions coincide, so the displacement is zero.
To summarize:
- Distance covered: 100 meters
- Displacement: 0 meters
