Can be magnitude of a vector have negative value?
Vectors have magnitude and direction. The magnitude is always a positive number.
Vector rm vec A points in the negative y direction and has a magnitude of 11 units Vector rm vec B has twice the magnitude and points in the positive x direction.?

Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
Can a vector resultant have a negative direction I have a statics problem and the answer is 77.31 deg in the III quad Negative or Positive Or is the answer 257.31 deg from the horizonal?
A vector has both magnitude and direction. The magnitude is always positive, by convention, but this is not cast in stone. So you can have in your case a positive magnitude with a direction 257.31 degrees, which is the same as a positive magnitude 77.31 degrees in quadrant III, but the first way is more conventional. One could also say a negative magnitude at 77.31 degrees, in which case the negative sign implies a 180 degree reversal. So there are many choices, and you seem to have a good handle on this.
Can a vector have positive and negative components?
Yes, a vector can have both positive and negative components. In a two-dimensional space, for example, a vector can point in a direction where one component (such as the x-component) is positive while the other component (the y-component) is negative. This allows the vector to represent a direction that combines movement in different quadrants of the coordinate system. Thus, vectors can effectively capture a wide range of directional information.
What is the direction of angular motion associated with a positive () sign?
The direction of angular motion associated with a positive () sign is counterclockwise.
Can be magnitude of a vector have negative value?
Vectors have magnitude and direction. The magnitude is always a positive number.
Consider two vectors F1 with magnitude 79 N inclined at 305 and F2 with magnitude 63 N inclined at 76 measured from the positive x axis with counterclockwise positive What is the magnitude?
The resultant magnitude is 60.659 N and its vectorial angle is 356.6124 degrees.
Why can velocity be negative but nonzero speed is always positive?
Velocity includes both speed and direction, so a negative velocity indicates motion in the opposite direction. Speed, on the other hand, is a scalar quantity representing the magnitude of velocity without regard to direction, and therefore is always positive.
Why the magnitude of a vector is always positive?
Magnitude is the absolute value which is always positive.--Edit: Magnitude is a scalar quantity thus regardless of the direction of the vector (which determines is positivity or negativity) the magnitude would be positive.Example: you take two steps forwards; the magnitude is two steps, regardless of it being forward or backwards (positive or negative)
Vector rm vec A points in the negative y direction and has a magnitude of 11 units Vector rm vec B has twice the magnitude and points in the positive x direction.?

What does positive velocity means?
Positive velocity refers to an object moving in the positive direction along its path. It indicates that the object is moving forward or in the direction of increasing position. Velocity is a vector quantity that includes both magnitude (speed) and direction.
Which direction does torque go?
Torque is a vector quantity represented by both magnitude and direction. The direction of torque is perpendicular to the plane formed by the force applied and the point of rotation. It follows the right-hand rule, where the direction of torque can be determined by curling your right hand around the axis of rotation in the direction of the force.
Can there be a positive acceleration and a negative acceleration?
Yes, acceleration can be positive and negative because acceleration is a vector. It has both direction and magnitude. The direction is what makes it positive or negative. Negative acceleration is usually called deceleration.
How will you multiply a vector by positive number?
A positive scalar multiplied by a vector, will only change the vector's magnitude, not the direction. A negative scalar multiplied by the vector will reverse the direction by 180°.

Is it possible for the magnitude of force to be negative?
No, the magnitude of force cannot be negative. Force is a vector quantity, meaning it has both magnitude and direction. The magnitude of force is always a positive value, representing the strength of the force applied.
