POINTS TO REMEMBER (Motion & Time)

Motion: When an object changes its position with elapse of time in respect to a stationary object, such as a building, electric pole, etc., the object is said to be in motion.

Slow and Fast Motion: If an object A covers more distance and object B covers less distance in same time, then object A is called in Fast Motion and object B is called in Slow Motion.

Rectilinear Motion: Motion along a straight line is known as RECTILINEAR MOTION OR MOTION ALONG A STRAIGHT LINE.

Curvilinear Motion: Motion along a curve line is known as CURVILINEAR MOTION.

Circular Motion: Motion along a circle is known as CIRCULAR MOTION.

Speed: Distance covered by an object in unit time is called speed. This means Speed is equal to Distance upon Time.

Uniform Speed: If an object covers a fixed distance in each unit of time the motion is known as UNIFORM MOTION or UNIFORM SPEED.

Non-uniform Speed: If an object does not cover a fixed distance in each unit of time the motion is known as NON-UNIFORM MOTION or NON-UNIFORM SPEED.

Average Speed: Total distance covered divided by total time taken is known as AVERAGE SPEED.

Periodic Motion or Oscillatory Motion: When an object repeats its motion after every fixed interval of time, the motion of the object is called PERIODIC MOTION OR OSCILLATORY MOTION.

Oscillation: The motion of pendulum starting from one extreme end to another extreme end and back to the first extreme end is called one oscillation.

Time Period: Time taken to complete one oscillation by the pendulum is called time period.

Unit of Time: Time is measured in second.

Unit of speed: Unit of speed is meter/second (m/s).

Speedometer: A device used to measure the speed of a vehicle is called SPEEDOMETER.

Odometer: A device used to measure the distance covered by a vehicle.

Distance time graph of a moving vehicle with a constant speed is a straight slanting line.

Speed-time graph for the same vehicle will be a straight line parallel to x-axis.

A. Answer the following Questions

(Physics)- 1. Explain whether the walls of a classroom are at rest or in motion.

2. The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is

the distance moved by the car, if at 08:50 AM, the odometer reading has changed to

57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in

km/h also.

3. Give Reasons:

(i) The time measured by quartz clocks is much more accurate than that by the clocks

available earlier.

(ii) Average speed is same as actual speed in case of a body having uniform motion.

4. What are different types of speed?

5. Figure given here shows the distance-time graph for the motion of two vehicles A and B.

Which one of them is moving faster?

6. Which of the following distance-time graphs shows a truck moving with speed which is not

constant and why?

7. The distance between two stations is 240Km. A train takes 4 Hours to cover this distance.

Calculate the speed of the train in Km/h and m/s.

(Chemistry)-

8. Explain why rusting of iron objects is faster in coastal areas than in deserts.

9. Burning of candle is a physical change, chemical change or both .Explain.

10. Why does an apple slice acquire brown colour if kept in air for longer time?

(i) Why Binny was suffering from toothache?

(ii) What is the message you get from Binny’s Action?

(iii) Suggest one more method(other than those mentioned above) to control cavity

formation.

19. Raman’s mother does not allow him to talk while eating. She also does not allow him to eat

food while lying down. What could be the reason for it?

20. Which food will take longer to get digested- Glucose or Beans? Give Reasons.
