Describe what is meant by scalar and vector quantities, giving examples, Distance as an example of a scalar quantity and displacement as an example of a vector quantity, Describe how a vector quantity can be represented by an arrow, examples and step b
To deal with vector quantities a new branch of mathematics called vector analysis has been developed.Define scalar and vector quantityPhysical quantities are classified into two: scalars and vectors.The physical quantities which have only magnitude but no direction are called scalar quantities or ...
In physics, a vector is a quantity with a magnitude and a direction. This lesson will explore the ways in which vector quantities are used and it...
This lesson defines what a vector is in math and geometry. This lesson will also cover vector operations with examples.
For now, let’s go ahead and learn the two important techniques of vector multiplication. How to multiply vectors? When we multiply two or more vectors, it is important to determine whether we want a product that has a scalar quantity or vector quantity. The technique we’ll need to appl...
Still, to expand and develop the use of vectors in more realistic applications, it is essential to explain the vectors in terms of three-dimensional planes. A 3-D vector is defined as: “A three-dimensional vector is a line segment drawn in a 3-D plane having an initial point referred ...
Also, speed is a quantity that has magnitude but no direction. This is the basic difference between speed and velocity. Vector Notation As we know already, a vector has both magnitude and direction. In the above figure, the length of the line AB is the magnitude and head of the arrow po...
There are two ways to take a vector product. One is by taking their dot product, which yields a scalar, and the other is by taking their cross product, which yields another vector. Which product is used depends on the particular scenario and what quantity you are trying to find....
One important thing to be aware of up front: While torque can be thought of as a force in terms how it affects objects, it actually has units of work, or force times distance. However, torque is a vector quantity. A net torque (which you can think of as "total torque," as...
Learn about vector diagrams in physics and understand the basics of vectors and how they work. Explore how to draw a vector diagram and add and...
