Under what condition will the magnitude of the displacement be equal to the distance travelled by an object ?
When an object moves along a straight line in one direction.
A body can have zero average velocity but not zero average speed. Justify giving an example.
What can you say about the motion of an object whose distance time graph is
$(i)$ a straight line, parallel to the time axis ?
$(ii)$ a straight line passing through the origin making an angle with the time axis ?
A body is thrown vertically upward with velocity $u$, the greatest height $h$ to which it will rise is,
Study the speed-time graph of a car given below and answer the questions that follow
$(i)$ What type of motion is represented by $OA$ ?
$(ii)$ What type of motion is represented by $A B$ ?
$(iii)$ What type of motion is represented by $BC$ ?
$(iv)$ What is the acceleration of the car from $O$ to $A$ ?
$(v)$ What is the acceleration of the car from $A$ to $B$ ?
$(vi)$ What is the retardation of car from $B$ to $C$ ?
If the displacement-time graph for a particle is parallel to displacement axis, what is the velocity of the particle ?
