Scalars and Vectors-FAQs
What do you mean by Scalars and Vectors, in physics?
Scalars are the physical quantities that have magnitude or size only. While vectors are the physical quantities that have both magnitude and direction.
What are examples of Vectors Quantities?
Here are some important examples of vectors quantites are:
- Velocity
- Force
- Pressure
- Displacement
- Acceleration
- Thrust
What are some Scalar Quantities?
Here are some important examples of scalars are:
- Mass
- Speed
- Distance
- Time
- Area
- Volume
Is Force is a Scalar or a Vector Quantity?
Since force is a physical quantity that has both magnitude and direction. Therefore, it’s a vector quantity.
What is Difference Between Distance and Displacement?
The main difference between distance and displacement is that the distance has magnitude only and is a scalar quantity. However, displacement has both magnitude and direction so it is a vector quantity.
Scalar and Vector
Scalar and Vector Quantities are used to describe the motion of an object. Scalar Quantities are defined as physical quantities that have magnitude or size only. For example, distance, speed, mass, density, etc.
However, vector quantities are those physical quantities that have both magnitude and direction like displacement, velocity, acceleration, force, etc. It should be noted that when a vector quantity changes its magnitude and direction also change similarly, when a scalar quantity changes, only its magnitude changes.
