Motion & Time

S.I unit of time

• s/m

• m/s

• km/h

• m/mm

Boojho walks to his school which is at a distance of 3 km from his home in 30 minutes. On reaching he finds that the school is closed and comes back by a bicycle with his friend and reaches home in 20 minutes. His average speed in km/h is

• 8.3

• 7.2

• 6.3

• 9.2

Speed =

• distance covered

• distance covered X time taken

• distance covered / time taken

• time taken / distance covered

A distance time graph has distance as .............

• x and Y axis

• x axis

• Y axis

Device used to measure speed of a car is

• graph

• odometer

• speedometer

• none

What can you depict from the graph?

• object is in uniform motion

• object is in non uniform motion

• object has constant speed

• object is stationary
