Why vector quantities cannot be added and subtracted like scalar quantities?
Mainly because they aren't scalar quantities. A vector in the plane has two components, an x-component and a y-component. If you have the x and y components for each vector, you can add them separately. This is very similar to the addition of scalar quantities; what you can't add directly, of course, is their lengths. Similarly, a vector in space has three components; you can add each of the components separately.
Give two examples of vector quantities?
Velocity, acceleration, displacement, there are a lot.
What are two exambles of vector quantities?
A vector quantity is any measurement where the direction is relevant, such as position, velocity, acceleration, force, electric field, etc.
What two quantities are needed to get a vector quantity?
A magnitude, and a direction. Or, components in two directions, often called "x-component" and "y-component".
What are the methods of adding and subtracting vector quantities?
adding vectorsTo add two vectors, s+z, simply move the vector z to the end of the vector s.subtracting vectorsTo find the magnitude and direction of the difference between two vectors, s-z, simply draw a vector from z to s
Which of this two quantities is not a vector quantity magnetic field or charge?
Charge is not a vector.

What is the product of two vector quantities?
It depends on the type of product used. A dot or scalar product of two vectors will result in a scalar. A cross or vector product of two vectors will result in a vector.

What is the result of two vector quantities acting in the same direction?
The result R is in the same direction.
What are two exambles of vector quantities?
A vector quantity is any measurement where the direction is relevant, such as position, velocity, acceleration, force, electric field, etc.
Type of quantity?
there are two types of quantities - Scalars and vectors. Scalars are quantities which intrinsically have the property of magnitude only. Vectors are quantities which intrinsically have both the properties of magnitude and direction.
Vector addition allows you to add what two quantities for any number of vectors?
Ion Know ... You Tell Me
For two vector quantities to be equal they must have the same direction and the same?
Same direction and equal magnitudes.
What two quantity are necessary to determine a vector quantity?
Magnitude and direction
If you have selected a coordinate system you can express a two-dimensional vector using a pair of quantities known collectivelly as?
Components.
What is parallelogram law of vectors?
"If two vector quantities are represented by two adjacent sides or a parallelogram then the diagonal of parallelogram will be equal to the resultant of these two vectors."
