Question

Select the odd one
a) Distance b) Speed c) Velocity d) Time

Answer 1

The Odd One is VELOCITY.

Reason:

• All the quantities (except Velocity) is a scalar quantity.

• Distance , speed and time are scalar quantities having only magnitude and no directions.

• But Velocity is a vector quantity having both magnitude and direction.

Additional information:

• Distance refers to the total path length travelled by an object. It is always positive and never negative.

• Speed refers to the the ratio of total Displacement to the total time taken , hence also positive and never negative.

• But , Velocity is given by Displacement divided by time , hence can be negative , zero or positive.

Hope It Helps.

Answer 2

Answer:

velocity is odd from other quantities. other quantities are scalar.

velocity is a vector quantity.

Scalar quantity = scalar quantity only has magnitude.they don't have direction.  

they follow simple rules of an algebraic method for sum, addition, and multiplication.

other examples of a scalar quantity  

• temperature  

• time  

• speed  

vector quantities = vector quantities are those which have both magnitude and direction. if you add our subtract they follow vector addition and subtraction rules.  

examples of vector quantity =

• distance

• force

• acceleration

• momentum
