differencses between scalar and vector quantities?

Answer 1

Scalars are quantities that have magnitude only; they are independent of direction. Vectors have both magnitude and direction. The length of a vector represents magnitude. The arrow shows direction. EO 1.1 DEFINE the following as they relate to vectors: a. Scalar quantity b. Vector quantity Scalar Quantities Most of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time (minutes, days, hours, etc.) represent an amount of time only and tell nothing of direction. Additional examples of scalar quantities are density, mass, and energy. Vector Quantities A vector quantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities

Difference Between Scalar And Vector

Answer 3

Scalar quantities only have a magnitude, while vector quantities have both magnitude and direction. Scalar quantities cannot be negative, I think. Maybe an example will help. A scalar quantity is speed. Therefore we can say speed = 5 meter per second. But a vector quantity is velocity. Velocity is 24meter per second, east. That way, speed only shows the magnitude like (5meter per second). But velocity shows both magnitude (24 meter per second) and direction (East).

Scalar is a physical quantity which has magnitude but no direction. Eg. length, mass,time, temparature etc. The above physical quantities remain same in whichever direction they are held or directed. So, direction doesn't play any role in them. they are only determines by the magnitude like how long or how heavy or how hot or cold etc. Vector is a physical quantity which has both magnitude and direction. Eg. Force, velocity, momentum etc. These physical quantities are dependent on direction. They are governed by magnitude and direction too. When we express force or velocity, which direction its acting or moving is also important. So, lack and existence of direction is the main difference of Scalar and vector quantities.

Answer 5

Scalar has only value. Vector has both value and direction. An aero plane's travel from Chennai to Bangalore is a vector quantity, The temperature of a glassful of milk is scalar quantity.

Answer 6

a scalar quantity only has a magnitude. 38 miles, for instance.

a vector quantity has a magnitude and a direction, say 12 m/s heading 12 degrees north of east.

Answer 7

Scalar quantity has only magnitude but no specific direction
example:mass
vector quantity has both magnitude and direction
example:displacement

Answer 8

scalar quantity :

it a quantity that has no direction. it has only magnitude.

ie, like the weight of an object. it has no direction, only magnitude.

some eg. for scalars are : mass of an object.

vector quantity :

it is a quantity that has both direction and magnitude.

some egs are : acceleration.

Answer 9

Scalar quantities are just an amount like speed...

Vector quantities contain both an amount and a direction, e.g. force, momentum, velocity, etc.

Answer 10

Difference
1. Scalers have magnitude only but hte vextors have directions also.
2. Another important things is that Vectors must follow the triangle or parallelogram law. Otherwise they will be trated as scaler.
For example, Current I is scaler thoughit has directions to specify but dont follow the traingle law.
