1
The concept of the body movement means..........
2
When car (A) covers the same distance as car (B) at the same time, this means that...........
3
When car (A) covers smaller distance than car (B) at the same time span, therefore...........
4
The two factors which can be used to describe the motion of a body are the..........
5
The distance covered by a moving body through a unit time is called the......... of the object.
6
Speed equals.......
7
Speed measurement unit is...........
8
A moving bus covers a distance of 500 m in 25 sec. so, its speed equals............
9
When a moving object covers equal distances in equal periods of time. this means that the body moves with...........
10
If the speedometer of a moving car points to 90 km/h, therefore after two hours the car covers..........
11
A runner covers a distance of 100 metres of a straight track in 10 seconds, so its speed equals...........
12
If the uniform speed of a car is 72 km/h so. its speed (in m/s) equals..........
13
If the uniform speed of a car 300 metres in a half minute, then its speed equals......... metre/second.
14
If the uniform speed of a car is 108 kilometres/hour so, its speed equals......... m/s.
15
A car moves at a regular speed equals 90 km/h, this means that the car covers a distance equals......... metres in 40 sec.
16
When the body covers equal distances at unequal intervals of time, this means that the body moves at.......
17
In case of motion that is described as movement at irregular speed, in this case, it is useful to refer to another term which is the........ speed.
18
A student takes a time of 10 minutes to from his home to the school at an average speed equals 2 m/s. Which of the following equals the distance between his home and the school?..........
19
A person takes a time of 10 minutes to transfer from home to work moving at an average speed of 3 m/sec. Which of the following equals the distance between home and work ?...........
20
A car moving on a straight line covers a total distance (d) in a total time (t), the average speed of the car is given by........
21
A runner ran the 1st 100 metres of a race in 8 seconds and the 2nd 100 metres in 12 seconds therefore, his average speed during the whole race is.........
22
The speed of a moving object relative to an observer in another moving object is called ......... speed.
23
If car (A) moves at speed 40 km/h and car (B) moves at speed of 50 km/h in the same direction, the speed of car (B) relative to a passenger in care (A) is..........
24
If the relative speed of a car is 50 km/h relative to an observer in a bus moves obs. in the same direction at 70 km/h, therefore the actual speed of this car is........
25
If car (A) moves at speed 80 km/h and car (B) moves at speed of 50 km/h in the same direction, the speed of car (A) relative to a passenger in car (B) is ........... km/h.
26
The relative speed of a moving object relative to an observer moves at the same speed in the opposite direction is.......... the actual speed.
