# Vector quantity - What is Vector Quantity? (With Examples)

### Is Power a Vector or Scalar Quantity?

Some examples of scalar quantities are temperature, volume of an object, length, mass, and time, among others.

Both are moving with the velocity of V1 in the east and V2 moving in the west, respectively, having the same linear momentum.

The force will be specified completely only if its direction is also specified.

Solution: The values for the two terms a and b are given in three axes of x-axis, y-axis and z-axis.

Hence, we can conclude, the physical quantityโEnergy is NOT a Vector Quantity.

Now, as we know, force and displacement both are vector quantities as it also requires direction to get the full detail of it.

Power: Scalar or Vector Now, our question is whether power is a vector or a scalar.

As we have studied that the energy, a physical quantity falls in the category of scalar quantity.

Description: But, The addition or subtraction of the quantity is done by using ordinary law of algebra not vector algebra.

The interesting feature of the dot product is that the resultant vector lies in the same plane.
Here are a few points which distinguish scalar and vector quantities.

In physics, a vector is a quantity with a magnitude and a direction. Magnitude is similar to absolute value in that it only cares about how far a quantity is from 0. Direction is stated, most .

So to define a vector quantity, it is a measuring quantity that requires two things: magnitude and direction. Magnitude as the numerical value and direction to know which the numerical value is headed. There are diverse examples for vector quantity such as momentum, linear momentum, acceleration, displacement, angular velocity, force, etc.

A vector quantity is a quantity of something which possesses both magnitude and direction. Magnitude is simply the size or amount of the quantity. For example, the magnitude of the quantity eight miles per hour is eight. Direction is meant in the ordinary sense, where the quantity is headed.

In mathematics and physics, vector is a term that refers colloquially to some quantities that cannot be expressed by a single number, or to elements of some vector spaces .
