Can you suggest the kind of motion of a body from the following distance – time graph?

उत्तर

Distance – time graph in the figure shows that initially, the body is in uniform motion i.e. it covers equal distance in equal intervals of time.
From O to A, the body is in uniform motion, and from A to B, the body is at rest.

An ant travels a distance of 8 cm from P to Q and then moves a distance of 6 cm at right angles to PQ. Find its resultant displacement.


How is the distance related with time for motion under uniform acceleration such as the motion of a freely falling body?


A body is moving in a straight line and its displacement at various instants of time is given in the following table 

Time (s) 0 1 2 3 4 5 6 7
Displacement (m) 2 6 12 12 12 18 22 24

Plot the displacement-time graph and calculate

(i) Total distance travelled in the interval 1 s to 5 s.

(ii) Average velocity in time interval 1 s to 5 s.


Figure given below shows a velocity-time graph for a car starting from rest. The graph has three parts AB, BC and CD.

Compare the distance travelled in part BC with the distance travelled in part AB.


A body starts with an initial velocity of 10m s-1 and acceleration 5 m s-2. Find the distance covered by it in 5 s.


When brakes are applied to a bus, retardation produced is 25 cm s-2 and the bus takes 20 s to stop. Calculate -

  1. The initial velocity of the bus
  2. The distance travelled by bus during this time.

A car travels a distance 100 m with constant acceleration and average velocity of 20 ms-1. The final velocity acquired by the car is 25 ms-1.

Find

(i) The initial velocity.

(ii) Acceleration of the car.


Name the physical quantity associated with the rate of change of displacement with time.


A particle is moving in a circular path of radius r. The displacement after half a circle would be


State whether true or false. If false, correct the statement.

Distance covered by a particle never becomes zero but displacement becomes zero.
