Practice Measurement of Time and Motion Class 7 Questions and Answers with Stepwise Solutions

1. Multiple choice questions.

1. Which of the following was used in ancient times to measure intervals of time during the day?

(a) Thermometer
(b) Odometer
(c) Sundial
(d) Barometer

Answer: (c) Sundial.

2. The SI unit of time is:

(a) hour
(b) minute
(c) second
(d) millisecond

Answer: (c) second.

3. Which device is used in vehicles to measure the distance travelled?

(a) Thermometer
(b) Odometer
(c) Barometer
(d) Speedometer

Answer: (b) Odometer.

4. In a simple pendulum, what happens to the time period if we increase the length of the string?

(a) Remains the same
(b) Decreases
(c) Increases
(d) Doubles

Answer: (c) Increases.

2. Very Short Answer (VSA).

1. What is a stopwatch used for?

Answer: A stopwatch is used for measuring short intervals of time very accurately, such as timing races in sports events.

2. Define speed in simple words.

Answer: Speed is the distance covered by an object in a unit time, usually measured in metres per second (m/s) or kilometres per hour (km/h).

3. Name two devices used in vehicles to measure speed and distance.

Answer: Speedometer is used to measure speed, and odometer is used to measure distance travelled by vehicles.

4. What is the function of the Ghatika-yantra?

Answer: The Ghatika-yantra was a water clock used in ancient India to measure fixed intervals of time by using a bowl that sank in water.

3. Short Answer Questions.

1. Explain the difference between uniform and non-uniform motion with examples from daily life.

Answer: In uniform motion, an object covers equal distances in equal intervals of time, like a train moving at constant speed. In non-uniform motion, speed varies, such as a car moving through city traffic, sometimes going fast and sometimes slowing down.

2. How can you make a simple water clock at home? Briefly describe the steps.

Answer: Take a plastic bottle, cut it in half, and make a hole in the cap. Place the top half upside down over the lower half. Fill the top with water. As water drips, mark the level at regular intervals using a watch to measure time.

3. A car travels 150 metres in 10 seconds. Calculate its speed in m/s and then convert it to km/h.

Answer:

Speed in m/s = $\frac{150}{10} = 15$ m/s
Convert to km/h: $15 \times 18/5 = 54$ km/h

4. Why are atomic clocks considered more accurate than pendulum clocks?

Answer: Atomic clocks use the vibrations of atoms, which are extremely regular and very fast. This makes them much more accurate, losing only about one second in millions of years, while pendulum clocks may lose several seconds per day.

5. Two trains travel the same distance. Train A covers it in 2 hours, and Train B in 1.5 hours. Which train is faster and what is the formula you use?

Answer: The train that takes less time is faster. Formula: Speed = distance / time. Since Train B covers the distance in less time, it is faster.

4. True or False Questions.

1. Odometer is used to measure the temperature of an object.

Answer: False.

2. The SI unit of speed is kilometre per hour.

Answer: False.

3. In uniform linear motion, equal distances are covered in equal intervals of time.

Answer: True.

4. The time period of a simple pendulum depends on the mass of the bob.

Answer: False.

5. Pendulum clocks were invented by Christiaan Huygens.

Answer: True.

3. Fill in the Blanks Questions.

1. The average speed of an object is the total _________ covered divided by the total time taken.

Answer: distance

2. Measurement of time in ancient days was done using devices such as _________ and water clocks.

Answer: sundials

3. A simple pendulum completes one _________ when its bob moves from one extreme position to another and back.

Answer: oscillation

4. The SI unit of time is _________ and its symbol is _________.

Answer: second, s.

5. A __________ is used to record very short intervals of time in sports events.

Answer: stopwatch
