what is the difference between ODOMETER and SPEEDOMETER ???
Plot a distance-time graph for a body travelling at a speed of 2.5m/s.
why do we multiply 5/18 or 18/5 when we convert?
What type of motion:
1. Soldiers ina march past.
2. Motion of a pendulum
why do we need to measure time?
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.
1) linear motion
When an object covers equal distance in unequal intervals of time, its speed is said to be ________
Difference between uniform motion & non-uniform motion?
Give any 2 examples of periodic motion to measure time.
At 7:00 a.m the odometre of the car reads 25777.what is the distance covered by the car and its speed when the clock reads 9:15 a.m and the odometre reads 25867?
What is oscillatory motion?

The discovery of which principle made the accurate measurment of time possible? What is the principle?
what is basic unit of speed?
With the help of the speedometer reading of a vehicle would be able find the distance travelled if the time is known ?
The rotation of the earth on its axis is periodic motion but not oscillatory. why?
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
Hands of an athlete in a race
Pedal of a bicycle in motion
Motion of the earth around the sun
Motion of a swing
Motion of a pendulum
what property of a simple pendulum makes it useful in measuring time?
A simple pendulum takes 20 seconds to complete 10 oscillations.
What is the time period of the pendulum?
define periodic events
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
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
The distance between Paula’s house and her school is 12 km. The distance between her school and the public library is 6 km, whereas the distance between the public library and her house is 15 km.
Paula reaches her school from home in half an hour and then takes another 15 minutes to reach the public library. She further takes 15 minutes to come back home from the public library.
What was Paula’s average speed during the entire trip?
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?
give reason: time measured by quartz clocks is much more accurate than that by the clocks avilable earlier
a cheetah runs adistance of 200m in 10sec .what is the speed of cheetah in km/hr?
1.Anobject travels 16min 4s and then another 16m in 2s. what is the average speed of object???
can you say me what are sundials, water clocks,and sand clock?
A cyclist is travelling with a uniform speed on a straight road. After traveling 700 m, one of the tyres of the cycle got punctured. He decided to cover the rest of the distance (300 m) by walking with the cycle. He covers the remaining 300 m in 7 minutes.
If the cyclist takes a total of 12 minutes to complete his journey, then what is his average speed during the journey?
a labelled diagram of simple pendulum and explain briefly

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?
What do you mean by Slow motion and Fast motion?
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.
