The concept of the body movement means........
constancy of its position with the change in time.
the change in its position with the time.
its speed.
its acceleration.
The two factors which can be used to describe the motion of a body are the
speed and time.
distance and time.
area and time.
displacement and speed.
The distance covered by a moving body through a unit time is called the ....... of the body.
weight
density
speed
Motion
Speed equals
distance÷ time.
distance x time.
distance + time.
time ÷ distance.
Speed measurement unit is............
metre.second.
metre/second.
metre/second2
kg.
If a car and a bike moving from the same position and in the same direction, the speed of the car is 50 m/sec. and the speed of the bike is 10 m/sec., after 4 seconds. The distance between them becomes........meter.
100
160
200
240
When a moving object covers equal distances in equal periods of time, this means that the object moves at
uniform speed.
uniform acceleration.
average speed.
relative speed.
A car covers 180 metres in two seconds, so its speed equals
90 m/sec.
180 km/h.
25 km/h.
45 m/sec
In case of motion that is described as movement at an irregular speed, in this case, it is useful to refer to another term which is the ............ speed.
uniform
scalar
vector
average
The result of multiplying the speed of a body by the time.
