1
(Distance-time) graph for a regular motion at a constant speed is a...........
2
For a car moves at a regular speed, the ratio d/t...........
3
Which of the following graphs represents the movement of an object at a constant speed?...........
4
The graph (.........) represents an object at rest.
5
From the opposite graph, what is the speed of the car ?..........
6
On recording the results of an experiment in which an object moves, the results were as follows: This object moves at.........
7
Which of the following (speed-time) graphs describes the movement of an object moves at a constant speed?..........
8
If the body moves from rest at a uniform acceleration, so its final speed is determined from the relation..........
9
The uniform acceleration means that the object speed......... by equal values through equal periods of time.
10
When an object speed increases, the movement is described as........
11
Decelerating motion means the........
12
Acceleration is the.........
13
The object moves at a constant uniform speed, this means that..........
14
A car moves at a speed 30 m/sec., then its speed changes to 60 m/sec. after three seconds so, the acceleration at which the car moves is.........
15
If the object at rest constancy moves regularly until its speed reaches 12 m/sec, after three seconds from starting motion so, the acceleration equal........ m/sec²
16
Acceleration measurement unit is...........
17
If a boat starts to move from rest till its speed becomes 2.5 m/sec. through 0.5 sec. so, the acceleration of the moving boat is..........
18
The ratio between the final speed and the initial speed of an object moves at an accelerating motion is...........
19
The ratio between the final speed and the initial speed of an object moving in a straight line in a decelerating motion (a negative acceleration) is ...........
20
When the final speed of a moving object is less than its initial speed, therefore the object motion is described as...........
21
Movement is at a uniform acceleration...........
22
Which of the following graphs represents the motion of a body at a uniform acceleration ?...........
