Case Study Questions on Measurement of Time and Motion

Case Study Question 1:

Passage: The Swing and the Pendulum

Anita and Mansi sat on swings in the playground. Anita noticed that the swing moved back and forth in equal intervals. Their teacher explained that a swing behaves like a simple pendulum. Each complete back-and-forth motion is called an oscillation. They used this swing motion to measure time and compare it with their wristwatches.

Q1. What is one complete to-and-fro motion of a pendulum called?
(a) Rotation
(b) Revolution
(c) Oscillation
(d) Cycle

Answer: (c)
Difficulty Level: Easy
Explanation: A full back-and-forth movement of a pendulum is known as one oscillation.

Q2. Which instrument works on the principle of oscillations?
(a) Thermometer
(b) Water clock
(c) Pendulum clock
(d) Compass

Answer: (c)
Difficulty Level: Moderate
Explanation: Pendulum clocks keep time using the regular oscillations of a pendulum.

Q3. The time taken for one oscillation is called:
(a) Frequency
(b) Period
(c) Speed
(d) Pulse rate

Answer: (b)
Difficulty Level: Moderate
Explanation: The time taken to complete one oscillation is called the time period.

Q4. If a pendulum completes 20 oscillations in 10 seconds, what is the time period of one oscillation?
(a) 0.2 seconds
(b) 2 seconds
(c) 0.5 seconds
(d) 10 seconds

Answer: (c)
Difficulty Level: Tough
Explanation: Time period = Total time / Number of oscillations = 10 ÷ 20 = 0.5 seconds.

Case Study Question 2:

Passage: Racing and Speed Analysis

During sports day, Raju ran 100 metres in 20 seconds while Priya completed the same in 25 seconds. Their teacher used this to explain the concept of speed, calculated as distance divided by time. Later, students plotted their performances on a graph and found that while Raju ran at a constant speed, Priya ran slower at the beginning and faster toward the end.

Q1. What is the formula for speed?
(a) Speed = Distance × Time
(b) Speed = Time ÷ Distance
(c) Speed = Distance ÷ Time
(d) Speed = Acceleration × Distance

Answer: (c)
Difficulty Level: Easy
Explanation: Speed is calculated as the distance travelled divided by the time taken.

Q2. If Raju runs 100 m in 20 seconds, what is his speed?
(a) 5 m/s
(b) 0.2 m/s
(c) 20 m/s
(d) 2 m/s

Answer: (a)
Difficulty Level: Moderate
Explanation: Speed = Distance ÷ Time = 100 ÷ 20 = 5 m/s.

Q3. A graph showing equal distances covered in equal intervals indicates:
(a) Irregular motion
(b) Increasing speed
(c) Uniform motion
(d) Decreasing time

Answer: (c)
Difficulty Level: Moderate
Explanation: Uniform motion means the object moves equal distances in equal times.

Q4. Which of the following indicates non-uniform motion?
(a) Steady speed
(b) Oscillation
(c) Unequal distances in equal time intervals
(d) Constant velocity

Answer: (c)
Difficulty Level: Tough
Explanation: Non-uniform motion means unequal distances covered in equal intervals of time.
