When an object covers equal distance in unequal intervals of time, its speed is said to be ________

why do we need to measure time?

give reason: time measured by quartz clocks is much more accurate than that by the clocks avilable earlier

a car moves with a speed of 40km/h for 15 minutes then with a speed of 60 km/h for next 15 minutes.find the total distance covered by the car in these 30 minutes.

Define:-1) linear motion2)Circular motion3)periodic motion4)Oscillatory Motion5)Rotational motiona) Sand clock

b) Sundial

c) Pendulum clock

d) Water clock

Which option is correct??

a 108 km/hr into m/s

b 40 m s to km/hr

what are the importance of distance time graph?

Measuring time is more difficult than measuring length.Do you agree ? Give reasons

what are the quantities that can be measured called ?If the length of a pendulum is increased four times, its time period will become

accurate measurements of distance , mass and so on were made much before accurate measurement of time became possible why?

the swing of a pendulum gradually decreases with time . however , even then it is regarded as a reliable time keeping deviceWhen an object moves on a straight line with a constant speed it is called a uniform motion. Then , if an object ic moving on circular path with a constant speed is it also be known as uniform motion ? explain.
