Is work and energy scalar or vector quantities explain?
It is scalar. This simply means that - unlike vector quantities - energy is not defined in a particular direction.
Which measurement is a vector quantity?
A vector quantity measures the movement of a particular object in a given direction. An example of a vector quantity is velocity.
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
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.

Is it possible to add the component of a vector to the sane vector?
Yes, in which case the resulting vector is twice the length of the original, pointing in the same direction.
What is the speed of an object moving on a particular direction?
The speed of an object moving in a particular direction is called the velocity and it's a vector, that is, it has magnitude and direction. Speed is the scalar part of velocity.
What does the pointing vector represent?
A vector already points, without needing an extra. I wonder if you mean "Poynting Vector" which shows the direction and magnitude of power flow in radiation.
When do you need to use component method for vector addition?
when the vectors are not all pointing in the same direction
What is the direction of resultant vector when a vector of 25 units south is added to a vector 25 units east?
50
Why vector is staight not a curve?
Because a vector contains information about the direction. A direction, at any particular position is the tangent to the curve and this, by definition, must be straight.
What Example of power flow by using pointing vector?
The direction of power flow is in the direction of the Poynting vector.The vector itself is the cross product of the Electrostatic field and the Magnetic field.P = E x H
When is the vector sum not equal in magnitude to the algebraic sum?
The magnitude of the vector sum will only equal the magnitude of algebraic sum, when the vectors are pointing in the same direction.
Speed of an object in a paticular direction?
Speed =distance/time Speed in a particular direction become velocity, a vector, which has magnitude and direction.
A vector always consist of?
A vector always consists of a direction and magnitude. For example, a vector representing the weight of an object that is 35N would be represented as an arrow pointing downward with a magnitude of 35N. You could also represent the weight of 35N as -35N, in which the negative symbol indicates a downward force.
Why force is consider as vector but not scalar?
Because a force always acts in a particular direction.
What is vector in math?
Simply put, a vector is 2 dimensional. Think of speed - it is only one dimensional. It is not a vector, it is a scalar. It is measured in a scale, most commonly noticed when inside a vehicle. You are travelling at 100km/h (60mph) Vectors are 2 dimensional, they have a magnitude and a direction. Think of velocity, as an arrow - imagine you are travelling at 60 mph in a northerly direction, your arrow would be pointing to the notth, with a magnitude of 60mph, If you were travelling at 60mph in a southerly direction, your velocity vector would be pointing towards the south, the exact opposite of your vector if you were travelling in a northerly direction. However the speed in these two scenario's, speed not being a vector, remains exactly the same, 60mph.
