This chapter presents definitions of vector and scalar quantities, geometrical representations of vectors, and differentiation of vectors. Any given vector may be regarded as the sum of any one of infinitely many pairs of vectors. Thus, a vector V may be regarded as the sum of each of the ...
Some physical quanties can be expressed by a single number, such as mass, temperature, volume, voltage, energy, pressure and charge. These are known as Scalars. Vector quantities need both a magnitude and direction. Examples include velocity, force, momentum, angular velocity and electric field....
Vector and scalar quantities ∙A vector quantity is one which has a magnitude (size) and a spatial direction.∙A scalar quantity has only magnitude (size). Topic 1: Measurement and uncertainties 1.3 – Vectors and scalars EXAMPLE: A force is a push or a pull, and is measured ...
Scalars are quantities that are described by magnitude and vectors are quantities that are described by magnitude and direction. Examples of scalars: speed, distance Examples of vectors: displacement, velocity, acceleration 10 ft is a scalar, but 10 ft NW is a vector. For each question ...
All measurable quantities in Physics can fall into one of two broad categories - scalar quantities and vector quantities. A scalar quantity is a measurable quantity that is fully described by a magnitude or amount. On the other hand, a vector quantity is
A scalar is a quantity that is fully described by a magnitude. For example, length, time, distance, and speed are all scalar quantities. Recap: Line Segment A line segment is a part of a line that is bounded by two distinct endpoints and contains every point on the line between its end...
Scalar quantities can be manipulated by the laws of arithmetic applicable to natural numbers. For example if I add 20 grams of sugar to a recipe and then add 20 grams more the result is 40 grams of sugar in the recipe. If I buy a liter (1000ml) bottle of water and drink 250 ml, ...
When working with scalar quantities, one would only be comparing differences in magnitude. This means calculating a scalar quantity will only require addition, subtraction, multiplication, or division of the magnitude. As an example, let's use money. Suppose I had $150 in my wallet, and I wen...

Performing Vector Addition and Scalar Multiplication Now that we understand the properties of vectors, we can perform operations involving them. While it is convenient to think of the vector uu=⟨x,y⟩=〈x,y〉as an arrow or directed line segment from the origin to the point(x,y),(...
