Rest and Motion
The minute hand of a wall clock is 10 cm long. Find its displacement and the distance covered from 10 a.m. to 10.30 a.m.
Examine the data given for the motion of two different objects A and B carefully and state whether the motion of the objects is uniform or non uniform. Give reasons.
Is it possible that the train in which you are sitting appears to move even though it is at rest?
A body thrown in the vertically upward direction rises up to a height 'h' and comes back to position from where it was thrown. Calculate
(a) The total distance travelled by the body.
(b) The displacement of the body.
A particle is moving in a circle of diameter 5m. What is its displacement when it completes 1 1/2 revolutions.
A particle moves 3m north, then 4m east and finally 6m south. Calculate the displacement.
An athlete completes one round of a circular track of diameter 49m in 20s. Calculate the distance covered and displacement at the end of 30s.
(a) Differentiate between distance and displacement.
(b) Under what conditions is the magnitude of average velocity of an object equal to its average speed?
A cyclist travels a distance of 4 km from P to Q and then moves a distance of 3 km at right angle to PQ. What is the displacement of the cyclist.
A circular track has a circumference of 1570 m with AB as one of its diameter. A scooterist moves from A to B along the circular path with a uniform speed of 5 m/s. Find the :
(a) distance covered by the scooterist,
(b) displacement of the scooterist (Given 3.14),
(c) time taken by the scooterist in reaching from A to B.
