Quick Chapter Recap: Measurement of Length and Motion

Before you begin the worksheet, recall the core ideas from NCERT Chapter 5. Measurement means comparing an unknown quantity with a standard unit. The International System of Units (SI) standardises measurements globally: length in metres (m), mass in kilograms (kg), and time in seconds (s). Smaller and larger units use prefixes — centimetre (1 m = 100 cm), kilometre (1 km = 1000 m), gram (1 kg = 1000 g), milligram (1 g = 1000 mg), minute (1 min = 60 s), hour (1 h = 3600 s). Motion is change in position. Rectilinear motion is straight-line movement (train on straight track, falling apple). Circular motion follows a circular path (Earth around Sun, merry-go-round). Periodic motion repeats at regular intervals (pendulum, swing). Speed tells how fast an object moves: Speed = Distance ÷ Time, measured in metres per second (m/s) or kilometres per hour (km/h). Converting units: multiply m/s by 3.6 to get km/h; divide km/h by 3.6 to get m/s. Always write units in your answers and show working steps for full marks.

SI base units: metre (length), kilogram (mass), second (time)
1 m = 100 cm = 1000 mm; 1 km = 1000 m; 1 kg = 1000 g
Rectilinear: straight line. Circular: curved path. Periodic: repeating at fixed intervals
Speed = Distance ÷ Time; Distance = Speed × Time; Time = Distance ÷ Speed
Always position your eye perpendicular to the scale to avoid parallax error

Section A: Multiple Choice Questions (1 mark each)

Choose the single best answer for each question. Write the letter (A/B/C/D) clearly. Each MCQ tests one concept from the chapter — SI units, types of motion, or the speed formula. Read every option carefully; often two options look similar but only one is correct. Do not spend more than 1 minute per MCQ. If you are stuck, make an educated guess and move on; you can return if time permits. These questions directly reflect the language and style of CBSE Class 6 Science Chapter 5 and are drawn from NCERT examples and exercises.

Q1. The SI unit of length is: (A) centimetre (B) metre (C) kilometre (D) millimetre
Q2. Which of the following is an example of periodic motion? (A) A car moving on a highway (B) A stone falling from a building (C) A child swinging on a swing (D) A bird flying in the sky
Q3. 1 kilometre is equal to: (A) 10 metres (B) 100 metres (C) 1000 metres (D) 10000 metres
Q4. A train moves in a straight line from Station A to Station B. This is an example of: (A) Circular motion (B) Periodic motion (C) Rectilinear motion (D) Random motion
Q5. The formula to calculate speed is: (A) Speed = Time ÷ Distance (B) Speed = Distance × Time (C) Speed = Distance ÷ Time (D) Speed = Distance + Time
Q6. The SI unit of mass is: (A) gram (B) kilogram (C) milligram (D) tonne

Section B: Fill in the Blanks (1 mark each)

Complete each sentence with the correct word or phrase from the chapter. Answers should be precise — use standard terminology from NCERT Class 6 Science Chapter 5. Spelling counts, so write carefully. These questions test your recall of definitions, units, and motion types. Do not leave any blank unattempted; even a partially correct answer may earn you marks under CBSE liberal marking in some schools. Aim to finish this section in under 5 minutes so you have ample time for longer questions.

Q7. The standard unit of time in the SI system is the __________.
Q8. Motion along a straight line is called __________ motion.
Q9. The distance between two cities is usually measured in __________.
Q10. A pendulum exhibits __________ motion because it repeats its swing at regular intervals.
Q11. To convert speed from kilometres per hour to metres per second, we __________ by 3.6.

Section C: Match the Following (1 mark per correct pair)

Match each item in Column A with the correct description or unit in Column B. Write your answers as pairs (e.g., 1–D, 2–A). Each option in Column B is used exactly once. This section tests your ability to link concepts with examples and units. Carefully read both columns before matching. Cross out used options in Column B to avoid confusion. These questions are framed to test understanding of motion types and measurement units covered in NCERT Class 6 Science solutions and notes.

Column A:
12. Rectilinear motion
13. Circular motion
14. Kilogram
15. Speed
16. Periodic motion
Column B:
A. Motion that repeats at regular intervals
B. SI unit of mass
C. Motion along a curved path at constant distance from a centre
D. Distance travelled per unit time
E. Motion in a straight line

Section D: Short Answer Questions (2-3 marks each)

Answer each question in 2 to 4 sentences. Use complete sentences, define terms where needed, and give one example if asked. Each answer should demonstrate understanding, not rote memorization. CBSE examiners award full marks when you explain the reasoning clearly. For numerical problems, always write the formula first, substitute values with units, calculate, and box the final answer with the correct unit. Aim for about 4 minutes per question. These questions mirror typical CBSE Class 6 Science term-exam short-answer items and are grounded in NCERT Chapter 5 content.

Q17. Why do we need standard units of measurement? Give two reasons. (2 marks)
Q18. Distinguish between rectilinear motion and circular motion with one example of each. (3 marks)
Q19. Define periodic motion and give two examples from daily life. (2 marks)
Q20. A cyclist covers 60 kilometres in 4 hours. Calculate the speed of the cyclist in km/h. (3 marks)
Q21. Convert 25 m/s into km/h. Show your working. (2 marks)

Section E: Long Answer and HOTS Questions (5 marks each)

These questions require detailed explanations, multiple steps, or higher-order thinking. Write in paragraphs, use subheadings if helpful, and draw labelled diagrams where asked. CBSE awards marks for clarity, logical flow, correct terminology, and completeness. For numerical HOTS problems, show every step: list knowns, write the formula, substitute, calculate, and interpret the result. Spend roughly 5 minutes per question. These are designed to test deep understanding and application — the kind of questions that separate good students from excellent ones in CBSE Science exams. Reference NCERT Class 6 Science Chapter 5 explanations and worked examples as you frame your answers.

Q22. Explain the difference between mass and weight. Why does your mass remain the same on Earth and the Moon, but your weight changes? (5 marks)
Q23. A car travels 150 km in 3 hours, then 100 km in 2 hours. Calculate (a) the total distance travelled, (b) the total time taken, and (c) the average speed for the entire journey. Show all steps. (5 marks)
Q24. Describe three types of motion with one real-life example for each. Draw a simple diagram to illustrate circular motion. (5 marks)

Section F: Case Study Question (4 marks)

Read the short case carefully and answer the sub-questions that follow. Case studies test your ability to apply chapter concepts to real-world scenarios — a format increasingly used in CBSE exams. Extract data from the passage, identify the type of motion or measurement involved, and perform calculations as required. Write concise, direct answers. Marks are split across sub-questions, so attempt all parts even if you are unsure about one. This question integrates multiple concepts from NCERT Class 6 Science Chapter 5: units, motion types, and speed calculation.

Common Mistakes to Avoid in Chapter 5 Questions

Students often confuse mass with weight — remember mass is matter (kg), weight is gravitational force (N). In speed problems, always convert minutes to hours or hours to seconds before calculating; mixing units yields wrong answers. When measuring with a ruler, never start from the edge — use the zero mark and read perpendicular to avoid parallax error. In motion-type questions, do not write vague answers like 'it moves in a line' — specify 'rectilinear motion' using the NCERT term. For periodic motion, ensure you mention 'repeats at regular intervals'; just saying 'repeats' is incomplete. In formula-based questions, show every step: write formula, substitute with units, compute, box final answer. Skipping steps costs method marks even if your final answer is correct. Finally, spelling counts in fill-in-the-blanks: 'rectalinear' or 'perodic' will be marked wrong. Practice writing key terms five times each to internalize correct spelling. Review your CBSE Class 6 Science Chapter 5 solutions and notes regularly to avoid these pitfalls.

Do not confuse mass (amount of matter, kg) with weight (force, N)
Always convert time units before calculating speed (e.g., 30 min = 0.5 h)
Use the zero mark on rulers, not the ruler's edge, for accurate length measurement
State motion types using NCERT terms: rectilinear, circular, periodic — not vague descriptions
In numerical problems, write formula first, substitute values with units, then calculate
Check spelling of scientific terms in fill-in-the-blanks (second, kilogram, rectilinear, periodic)
