Identify the types of motion in each case:
Example of motion
Types of motion
Along a straight line|circular|periodic
Soldiers in a march past
Bullock cart moving on a straight road

Pedal of a bicycle in motion
Motion of the earth around the sun
Motion of a swing
Motion of a pendulum
Plot a distance-time graph for a body travelling at a speed of 2.5m/s.
The rotation of the earth on its axis is periodic motion but not oscillatory. why?
a simple pendulum takes 32 s to complete 20 oscillations wat is the time period of a pendulum?
define motion ? there are how many types of motion define them by using examples
when an object said to be in uniform motion
what are the importance of distance time graph?
what os the difference between speedometer and odometer?how these can be used? any two examples.
How do we find acceleration and retardation from the graph??
Why do you think accurate measurement of time became possible much after accurate measurement of length and mass ?
THE SWING OF A PENDULUM GRADUALY DECREASES WITH TIME HOWEVER EVEN THEN IT IS REGARDED AS A RELIABLE TIME KEEPING DEVICE WHY
mcq questions tracing changes through a thousand years online
A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes.What is the total distance covered by the car?
Define time. What is the most ancient unit of time?Define it.
a cheetah runs adistance of 200m in 10sec .what is the speed of cheetah in km/hr?
If the length of a pendulum is increased four times, its time period will become
1.Anobject travels 16min 4s and then another 16m in 2s. what is the average speed of object???
justtify this statement "the time period of the pendulum can be changed."
(Hint:On what factors does the time peiod of a pendulum depend?)
a labelled diagram of simple pendulum and explain briefly
what are the quantities that can be measured called ?
Measuring time is more difficult than measuring length.Do you agree ? Give reasons
whether the time period of a given pendulum is constant or not ?
accurate measurements of distance , mass and so on were made much before accurate measurement of time became possible why?
A stone is dropped from a height 100m above the ground ...will it have uniform or non-uniform speed as it moves towards the ground....And please explain your answers.....
When 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.
give reason: time measured by quartz clocks is much more accurate than that by the clocks avilable earlier
What do you mean by Slow motion and Fast motion?

2. pendulum is the mother of watches and clocks
3. we need to measure

b 40 m s to km/hr
Measuring time is more difficult than measuring length.Do you agree ? Give reasons
whether the time period of a given pendulum is constant or not ?
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 deviceA stone is dropped from a height 100m above the ground ...will it have uniform or non-uniform speed as it moves towards the ground....And please explain your answers.....
