Homework Statement
if the alpha is larger than 90 degree ( which means the resultant F is lean towards -x axis , then the angle between the Ax and the line from Ax to A will be less than 90 , am i right ?
why , i can't visualize it??BvU said:No. It will be exactly 90##^\circ##
(the 90##^\circ## as indicated in figure 2-26 (a) )
If the force is lean towards negative x-axis , it means the angle between the force and positive x -axis is more than 90 degree, right ? then how is it possible for it to remain 90 degree?BvU said:No. It will be exactly 90##^\circ##
(the 90##^\circ## as indicated in figure 2-26 (a) )
ya , i mean the line from Ax to A, not about the line from the origin to A (i.e. A⃗ itself).BvU said:You were talking about the line from Ax to A, not about the line from the origin to A (i.e. ##\vec A## itself).
The direction of a cartesian vector refers to the orientation or angle at which the vector is pointing in relation to the coordinate axes. It is often represented by an angle measured from the positive x-axis in a counterclockwise direction.
The direction of a cartesian vector is typically represented by an angle, either in degrees or radians, measured from the positive x-axis. It can also be represented by a unit vector, which is a vector with a magnitude of 1 in the same direction as the original vector.
No, the direction of a cartesian vector is always positive and is measured in a counterclockwise direction from the positive x-axis. However, if the vector is pointing in the opposite direction, it can be represented by a negative angle.
The direction of a cartesian vector can be calculated by using trigonometric functions such as sine, cosine, and tangent. The angle can be determined by taking the inverse of these functions using the x and y components of the vector.
The direction of a cartesian vector is important in determining the overall movement or force of an object. It also helps in understanding the relationship between different vectors and their effects on a system. Additionally, it is essential in solving problems involving vector addition and manipulation.
