Like other scalar quantities, energy is the product of two factors (force and displacement, in this case). My name is Amit Patel. A position vector is taken relative to the origin of the coordinate system; that is, it exists at the end of a straight line that connects to the middle of an axis. A vector is a living organism that transmits an infectious agent from an infected animal to a human or another animal. Scalar Quantities or Scalars: The physical quantities which have magnitude only and which can be specified by a number and unit only are called scalar quantities or scalars. This cookie is set by GDPR Cookie Consent plugin. Examples of vectors include displacement, velocity, and acceleration.

Scalar and Vector Quantity Examples Examples of Scalar Quantities If a tower's height is 15 metres, then that tower's height is a scalar number since it only requires the magnitude of height to define itself. Some examples of physical quantities are time, the mass of an object, the weight of a liquid, the force applied to an object, and the electric current. For example, if I say that the height of a tower is15 meters,then the height of the tower is a scalar quantity as it needs only the magnitude of height to define itself. The unit and dimension of scalars and vectors are the same. Because it involves the force of gravity, weight has a direction (down) as well as magnitude. On the other hand, the knowledge becomes manageable with consistent study and comprehension.
