Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
What is the direction of the resulting vector if vector of 2 units North is added to a vector of 2 units South?

Can you graphically represent a vector which has magnitude but no direction?
If a quantity does not have a direction, its a scalar quantity, not a vector quantity.
How do you describe a vector?
A vector is a qunatity having a magnitude and direction.
Physical meaning of vector?
A quantity involving direction and magnitude is called physically vector A quantity involving direction and magnitude is called physically vector
How can a null vector be a vector if there is no direction?
It has magnitude 0 and a direction and obeys vector laws, so is a vector
Is a torque vector quantity?
Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.
Can a vector be represented in terms of unit vector?
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.
What is meant by negative vector?
It is a vector that has the opposite direction to the reference positive direction. (A vector is one point in space relative to another.) Negative vector is the opposite direction
How a vector represent distance and direction?
A vector is like an arrow. The length of the vector represents the magnitude (distance, speed, whatever) while the direction is shown by the direction of the arrow.A vector is like an arrow. The length of the vector represents the magnitude (distance, speed, whatever) while the direction is shown by the direction of the arrow.A vector is like an arrow.

The length of the vector represents the magnitude (distance, speed, whatever) while the direction is shown by the direction of the arrow.
Is north a vector direction?
"North" is a valid direction, but for a vector, you would also need a magnitude.
Is the acceleration of a rocket a vector or scalar?
It is a vector. A scalar has only magnitude. A vector has magnitude and direction.Acceleration is a vector because it has magnitude and direction. That's why an object can be said to be accelerating if it has a circular rotation and a constant speed; even though it's speed isn't changing, it's direction constantly is. Displacement (s), velocity (v), and acceleration (a), are vectors because they have both magntude and direction.
What is a vector composed of?
A vector is a quantity with a direction.
What is magnitude - like in a vector?
Here's a vector: "30 miles an hour, going north"The name of that vector is "velocity". It has a magnitude and a direction. Themagnitude of this velocity is 30 miles an hour. We usually call that "speed".The direction of this velocity is "north".The magnitude tells how big the vector is. The direction tells which way it points."30 miles an hour" is not a velocity. It's a speed. Speed is only the magnitude ofa velocity vector, because it has no direction. Once we know the direction, we canput it together with the magnitude, and we'll have a vector, called "velocity".
Is momentum downwards?
Momentum is a vector, the product of a scalar (mass) & a vector (velocity). As such, its direction is whatever direction the velocity vector has.
What is velocity and why is it a vector?
Velocity is an indication of a speed, including a direction. It is a vector because that is how a vector is defined (a magnitude, including a direction).
Is Speed is a vector quantitys?
Speed is not a vector quantity, because it has no direction. When you combine speed with a direction, then you have a vector, called "velocity".
