lesson 1

A runner covers 450 metres in 45 seconds. Find his speed.

• 8 m/sec

• 12 m/sec

• 10 m/sec

• 14 m/sec

A train starts to move at 7 o'clock in the morning, then what is the time of arrival if it moves at speed of 100km/h to cover the distance of 500 km.

A car moving in a uniform speed equals 80 km/h. Find its speed in m/sec.

• 25m/sec

• 22.22m/sec

• 20m/sec

• 30m/sec

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............. Metres

• 100

• 160

• 200

• 240

A car moves at a regular speed equals 90 km/h, this means that the car covers a distance equals............. Metres in 40 sec.

• 4000

• 25

• 2000

• 1000

The motion in one direction in a........... line is considered the simplest type of motion.

• Straight

• Curved

• Linear

• Rotatory

When the object covers the double of distance at the same time. So its speed................

• Decrease to quarter

• Decrease to half

• Increase to double

• Increase 4 times

A car moves at a regular speed equals 20 m/sec. This means the car covers...............m in the third second.

• 20

• 25

• 60

• 50

A moving car covers 180 km in two hours, so its speed is............ M/sec.

• 20

• 30

• 15

• 25

The change in the position of an object by the time passes relative (according) to the position of ankther fixed object.
