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

A moving bus covers a distance of 500 m in 25 sec., so its speed equals .....

• 200 m/sec

• 20 m/sec²

• 20 m/sec

• 20 m

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 ......... metre.

• 100
• 160
• 200
• 240

A train moves at a speed 100 km/h. this means that it covers a distance of 50 km within time ............. hour.

• 0.3
• 0.4
• 0.5
• 0.6

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 m
• 90 km
• 180 km
