Apr 23, 2019 · A scalar quantity is a physical quantity with only magnitudes, such as mass and electric charge. On the other hand, a vector quantity is a physical quantity that has both magnitudes and directions like force and weight. In this article, let us familiarize ourselves with vectors and scalars.

The physical quantities which have only magnitude are known as scalar quantities. It is fully described by a magnitude or a numerical value. Scalar quantity does not have directions. In other terms, a scalar is a measure of quantity. For example, if I say that the height of a tower is15 meters, then the height of the tower is a scalar quantity as i...
The physical quantities for whichboth magnitude and direction are defined distinctly are known as vector quantities. For example, a boy is riding a bike with a velocity of 30 km/hrin a north-east direction. Then, as we see for defining the velocity, we need two things, i.e. the magnitude of the velocity and its direction. Therefore, it represents a...
Let us have a look at the line segmentdrawn below. A vector quantity always has a starting point and an endpoint. The two endpoints of the given line segment are distinguishable as and. It represents a directed line segment The directed line segment with an initial point A and terminal pointB is symbolically denoted as AB in bold. The lengtha of th...
Nov 23, 2022 · In mathematics and physics, a scalar is a quantity that only has magnitude (size), while a vector has both magnitude and direction. Examples of scalar quantities include pure numbers, mass, speed, temperature, energy, volume, and time.
Learn and revise about vectors and how they can be can be added, subtracted and multiplied by a scalar with this BBC Bitesize GCSE Maths AQA study guide.
The scalar or Dot Product (the result is a scalar). The vector or Cross Product (the result is a vector). (Read those pages for more details.) More Than 2 Dimensions. Vectors also work perfectly well in 3 or more dimensions: The vector (1, 4, 5)
A vector is a quantity that has both a magnitude (or size) and a direction. Both of these properties must be given in order to specify a vector completely. In this unit we describe how to write down vectors, how to add and subtract them, and how to use them in geometry.

Oct 15, 2015 · Vectors are quantities that have magnitude (size) AND direction. For example: 35 m is a scalar quantity. 35 m [East] is a vector quantity. Quantities like temperature, time, mass and distance are examples of scalar quantities. Quantities like force, velocity, and displacement are examples of vector quantities.
