"The direction in which an object moves is given by the direction of velocity of the object and not by the direction of acceleration". Give an example to justify this statement
When an object is thrown upwards its velocity is directed upwards but the acceleration is directed downwards. Therefore, velocity determines the direction of motion.
Area under a $v -t$ graph represents a physical quantity which has the unit
Draw the distance$-$time graph for the following situations
$(a)$ When a body is stationary.
$(b)$ When a body is moving with a uniform speed.
$(c)$ When a body is moving with non$-$uniform speed.
Draw displacement$-$time graphs for the following situations
$(i)$ When body is stationary.
$(ii)$ When body is moving with uniform velocity.
$(iii)$ When body is moving with variable velocity.
Name a physical quantity that essentially changes as a body moves.
Define distance and displacement. A body covers one complete revolution around a circular park of circumference $176 \,m$ in $4$ minutes. Find the displacement of the body after $6$ minutes.
