Question

What is the difference between a scalar and a vector quantity?

Answer 1

• a scalar has magnitude only, while a vector has magnitude and direction
• Examples of scalar quantities include time, temperature, and mass, while examples of vector quantities include displacement, velocity and acceleration
• Scalars can be added and subtracted algebraically, while vectors require vector addition and subtraction

Answer 2

The main difference between scalar and vector quantity is that scalar quantity only have magnitude, while vector quantity have both magnitude and direction. 

Answer 3

Scalar and vector are two types of physical quantities in physics.

Scalar quantity refers to a physical quantity that has only a magnitude or size, but no direction. Examples of scalars are mass, temperature, time, distance, and speed. Scalar quantities are typically represented by a single number without any specific direction or orientation.

Vector quantity refers to a physical quantity that has both magnitude and direction. Examples of vectors are displacement, velocity, acceleration, and force. Vector quantities are typically represented by an arrow with the length representing the magnitude and the direction of the arrow representing the direction of the vector.

In summary, scalar quantities have only a magnitude, while vector quantities have both a magnitude and a direction.

Answer 4

A scalar quantity is a quantity that is described by a magnitude, such as temperature or speed. A vector quantity is a quantity that is described by both a magnitude and a direction, such as velocity or force.

Answer 5

A scalar quantity has only magnitude, while a vector quantity has both magnitude and direction. Examples of scalar quantities include mass and time, while examples of vector quantities include velocity and force.
