Ex 10.1, 3 Classify the following as scalars and vectors quantities. (i) time periodScalar : A quantity which has only magnitude, eg : 10 km
Vector: A quantity which has a magnitude as well as a direction
eg : 10 km towards north
Time period eg : 10 seconds has only magnitude i.e. 10 and no direction.
So, Time period is a scalar
Ex 10.1, 3 Classify the following as scalars and vectors quantities. (ii) distanceScalar : A quantity which has only magnitude, eg : 10 km
Vector: A quantity which has a magnitude as well as a direction
eg : 10 km towards north
Distance, eg : 5 meters has only magnitude 5 and no direction
So, Distance is scalar
Ex 10.1, 3 Classify the following as scalars and vectors quantities. (iii) forceScalar : A quantity which has only magnitude, eg : 10 km
Vector: A quantity which has a magnitude as well as a direction
eg : 10 km towards north
Example: 5N downward,
5 N downward has a magnitude as well as a direction
So, force is a vector
Ex 10.1, 3 Classify the following as scalars and vectors quantities. (iv) velocityScalar : A quantity which has only magnitude, eg : 10 km
Vector: A quantity which has a magnitude as well as a direction
eg : 10 km towards north
Eg : 5 m/s east
It has a magnitude, i.e. 5 m/s , and also a direction i.e. towards east.
So, velocity is a vector
Ex 10.1, 3 Classify the following as scalars and vectors quantities. (v) Work doneScalar : A quantity which has only magnitude, eg : 10 km
Vector: A quantity which has a magnitude as well as a direction
eg : 10 km towards north
Work done has only magnitude and no particular direction,
Therefore, work done is a scalar.
