AI Thread Summary
The discussion focuses on determining the x-component of a vector using the sine of its angle, specifically when the angle is measured from the vertical. Participants seek clarification on the relationship between two vectors when one vector's component along the direction of another is zero, indicating they are perpendicular. Additionally, questions arise regarding the implications of an object's average velocity being zero over a time interval, suggesting that its displacement is also zero. The conversation also touches on the definitions of velocity and average velocity, emphasizing the distinction between speed and velocity. Overall, the thread seeks to clarify fundamental concepts in vector analysis and motion.

pleasezzzzzzzz help me ...

in what circumstances is the x-component of a vector given by magnitude of a vector times the sine of its direction angle?
 
Physics news on Phys.org
When the angle given is with respect to the vertical (y-axis).
 
oh thank u so much...
 
can ny 1 help me with these questions?
If the component of vector A along the direction of vector B is zero, what can u about the two vectors?
 
Q:2
If the average velocity of an abject is zero in some time interval, what can u say about the displacement of the object for that interval?

Well, what do you think?
 
i hv no idea
 
what do you mean by component of vector A along the direction of vector B?

of course you must have some clue or idea.

can you draw two vectors that have no common component? What can you say about them? hint: look at angles.

Q2: What is the definition of velocity (speed and velocity is not the same), and average velocity?
