MOTION WORKSHEET 1

SECTION A
 
CONCEPTUAL QUESTIONS
 
 
1 What does the following represent:
 
i. Slope of the velocity – time graph
 
ii. Area under a velocity – time graph
 
2 What is the value of acceleration for a body at rest? 
 
3 The distance time graph of a body is a straight line parallel to the time axis. What information does the graph convey regarding the motion of the object?
 
4 Give an example of motion in which a body has constant speed but not constant velocity.
 
5 Can a v- t graph be perpendicular to time axis? Why? 
 
6 Three speed- time graphs are shown below.
 CBSE Class 9 Science Motion Worksheet Set H 1
 
Which graph represents the case of :
 
i. A ball thrown vertically upwards and returning to the hands of the thrower.
 
ii. A body decelerating to a constant speed and accelerating.
 
7 Define uniform circular motion. What is the direction of acceleration and velocity of an object moving along a circular path?
 
8 i. List two differences in tabular form between speed and velocity.
 
ii. When is a body said to have (a) uniform velocity (b) variable velocity?
 
iii. How the average velocity of a body is calculated when its velocity changes at a non-uniform rate?
 
9 A body moves around the sun with constant speed in circular path. Is the motion of the body uniform or accelerated?
 
10 Under what condition, the average speed of a moving object is equal to the  magnitude of the average velocity.
 
11. Figure shows distance- time graph of two objects A and B. Which object is moving with a greater speed when both are moving?

12 Derive graphically (i) position-time relation (ii) velocity – time relation for an object under uniformly accelerated motion.
 
13 The displacement of a moving object in a given time interval is zero. Would the distance travelled by the object also be zero? Justify your answer.
 
14 Draw the displacement- time graphs for an object (i) at rest (ii) in uniform motion
 
(iii) in uniformly accelerated motion.
 
15 What is the condition under which the distance and the magnitude of displacement are equal?
 
SECTION B

NUMERICALS

16 A car travels 100km at a speed of 60 km/h and returns with a speed of 40 km/h. Calculate the average speed for the whole journey.
 
17 A body starting from rest and moves along the x axis with constant acceleration 5m/ s2 for 8 seconds. If it then continues with constant velocity , what distance will the car cover in 12 seconds since it started from rest?
 
18 A car travels with a uniform velocity of 25 m/s for 5s.the brakes are then applied and the car comes to rest with uniform retardation in a further 10 s, then calculate the retardation produced and the total distance travelled in 15 s?
 
19 A car travelling at 36km/h speeds up to 72km/h in 5 s. What is its acceleration? If the same car stops in 20s, what is its retardation?
 
21 The velocity – time graph of a car is given below .The car weighs 1000kg.
 
i. What is the distance travelled by the car in the first 2 seconds?
 
ii. What is the retardation produced in the last second of motion of the car?
 
iii. What is the acceleration of the car during the time interval from 2 to 5 second? 22 A radar spots a plane. If radio pulse emitted by radar and reflected by the plane reaches back to ground station in 0.5 x103 s. What is the distance of the plane
from the radar station ? (speed of radio pulse is 3 x 108 m/s)
CBSE Class 9 Science Motion Worksheet Set H 3
 
23 A body moving with a velocity of 2 m/s acquires a velocity of 10 m/s in 5 s. Find its acceleration.
 
24 A body starting from rest travels with uniform acceleration .If it travels a distance of 100 m in 5 s, find the value of acceleration.
 
25 Which type of motion is represented by the velocity – time graph shown below? Name the physical quantity which can be calculated by the area of rectangle ABCD.
