Classify the following as scalar and vector quantities. (i)Time period (ii)Distance (iii)Force (iv)Velocity (v)Work done
(i)Time period is a scalar quantity as it involves only magnitude.
(ii)Distance is a scalar quantity as it involves only magnitude.
(iii)Force uis a vector quantity as it involves both magnitude and direction.
(iv)Velocity is a vector quantity as it involves both magnitude as well as direction.
(v)Work done is a scalar quantity as it involves only magnitude.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
In general, vectors are used in Maths and Science and are categorized into 10 different types of vectors such as:-
