What is the difference between uniform motion in a straight line and circular motion ?
Uniform linear motion | Uniform circular motion |
$(i)$ The body moves along a straight line. | $(i)$ The body moves around a circular path. |
$(ii)$ Acceleration js zero, as velocity remains constant. | $(ii)$ It is an accelerated motion, due to continuous change in velocity which happens due to change in direction. |
What conclusion can you draw from the displacement$-$time graph of a body shown below ?
The velocity$-$time graph of a truck is plotted below
$(a)$ Calculate the magnitude of displacement of the truck in $15$ seconds.
$(b)$ During which part of the journey was the truck decelerating ?
$(c)$ Calculate the magnitude of average velocity of the truck.
Name the force which is responsible for change in position or state of an object.
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.
If the displacement of a body is proportional to the square of the time elapsed, what type of motion does the body possess ?
