Vector displacement around a closed loop

In summary, a closed loop will always have a total vector displacement of zero, regardless of its dimensions or type. This means that when a vector moves around a closed loop, it will return to its original position and direction. This rule applies to both Euclidean and more general spaces.

My book says that the total vector displacement around a closed loop is zero. Is this a general thing for every type of closed loop?
If so, should this be obvious?

Well, it just means that you're back to the point where you started. So, the vector displacement is indeed zero. It's like moving from point A on the circumference of a circle and rotating around until you reach point A again. So, you had a certain scalar displacement (the value of the circumference of the circle) but the vector displacement is zero.

To answer your questions, yes, the rule applies to any kind of closed loop, which includes any dimensions, i think.

In a Euclidean space, moving a vector around a closed loop will return it to exactly the same vector. In a more general space, moving a vector around a closed loop will return to the same point but the vector may not be pointing in the same direction.

Thanks for this clarification, HallsofIvy.
 

1. What is vector displacement around a closed loop?

Vector displacement around a closed loop is the total change in position of an object as it moves around a closed path. It is represented by a vector, which has both magnitude and direction.

2. How is vector displacement around a closed loop different from scalar displacement?

Scalar displacement only considers the magnitude of the change in position, while vector displacement takes into account both magnitude and direction. This means that vector displacement can provide more detailed information about the movement of an object.

3. What is the importance of vector displacement around a closed loop in physics?

Vector displacement around a closed loop is important in physics because it helps us understand the motion and behavior of objects in a closed system. It can also be used to calculate other important quantities such as velocity and acceleration.

4. How is vector displacement around a closed loop calculated?

To calculate vector displacement around a closed loop, you must first measure the initial and final positions of the object and determine the change in position. Then, you can use vector addition to find the total displacement vector, taking into account the direction of movement around the loop.

5. Can vector displacement around a closed loop be negative?

Yes, vector displacement around a closed loop can be negative if the object moves in a direction opposite to the initial direction. This indicates that the object has moved backwards or in the opposite direction from its initial position.
