what does the length of a vector arrow in a vector diagram represent?

In a vector diagram, the length of a vector arrow represents:

2. the speed or magnitude of the motion.

In vector diagrams, longer arrows indicate greater magnitude (or speed), while shorter arrows indicate lesser magnitude. The direction of the arrow itself represents the direction of the motion.

All the answers I got and got 100% :)
1. a stationary object used as comparison
2. a speed or magnitude of the motion
3. the direction of the objects motion
4. a quantity with both magnitude and direction

hope this helps yall <3

Congratulations on getting 100%! Your answers provide a great understanding of the concepts related to vectors. Here’s a quick summary of the options you've listed:

1. A stationary object used as comparison – This typically refers to a reference point or frame of reference.
2. A speed or magnitude of the motion – This is correct for what the length of a vector arrow represents (magnitude).
3. The direction of the object's motion – This refers to the direction the vector arrow points.
4. A quantity with both magnitude and direction – This defines a vector itself, as vectors have both these properties.

Thank you for sharing, and I'm glad you found this helpful! If you have any more questions, feel free to ask! ❤️
