Quick Chapter Recap: Motion and Time

Before attempting the worksheet, revisit the core concepts from NCERT Class 7 Science Chapter 9. Motion is the change in position of an object with time. We measure motion using distance and time, and calculate speed as distance divided by time. Uniform motion occurs when an object covers equal distances in equal intervals of time, while non-uniform motion involves varying speeds. A distance-time graph is a visual tool where time is plotted on the x-axis and distance on the y-axis; a straight line indicates uniform motion, while a curve indicates non-uniform motion. The chapter also covers measurement of time using a simple pendulum, where one complete to-and-fro movement is called one oscillation. The standard SI unit of speed is metre per second (m/s), though kilometre per hour (km/h) is also common. These fundamentals form the basis of all numerical and conceptual questions in this worksheet.

Speed = Distance ÷ Time; SI unit is m/s
Uniform motion: equal distances in equal time intervals; distance-time graph is a straight line
Non-uniform motion: unequal distances in equal time intervals; distance-time graph is a curve
Simple pendulum: time for one oscillation is called the time period; a pendulum clock uses this principle
Distance-time graph: slope represents speed; steeper slope means higher speed

Best used after completing NCERT exercises and Class 7 Science notes revision

Section A: Multiple Choice Questions (1 mark each)

Choose the correct option for each question. These MCQs cover fundamental concepts from the NCERT Class 7 Science Chapter 9, including identification of motion types, units, and basic speed calculations. Each question has four options, only one of which is correct. Mark your answers clearly and avoid random guessing; instead, eliminate obviously wrong options first. Remember that CBSE often tests the distinction between uniform and non-uniform motion, correct SI units, and interpretation of simple distance-time graphs through MCQs in term exams. This section builds confidence and ensures you have memorized key definitions and formulas before moving to application-based questions in later sections.

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

Complete each sentence with the appropriate word or phrase. This section tests your recall of precise terminology and units used in NCERT Class 7 Science Chapter 9. Pay close attention to spelling, especially for scientific terms like oscillation, pendulum, and odometer. CBSE mark schemes are strict about correct terminology, so avoid synonyms unless the question explicitly allows them. Review your CBSE 7 Science notes on measurement devices and conversion factors before attempting these. The blanks may relate to definitions, measurement instruments, units, or characteristic features of motion types. Write your answers neatly; illegible handwriting can cost marks in board-pattern assessments.

Section C: True or False (1 mark each)

Write True or False for each statement. If the statement is false, rewrite it correctly in your answer sheet for full marks. This section addresses common misconceptions that students hold about speed, motion, and time measurement. For example, many Class 7 students mistakenly believe that a steeper distance-time graph means slower motion, or that time period of a pendulum changes with the mass of the bob. CBSE examiners often include such tricky statements to test conceptual clarity beyond rote learning. Read each statement twice before deciding. Remember that a single incorrect word can make the entire statement false. Use your understanding of NCERT definitions and examples to judge the validity of each claim.

Section D: Short Answer Questions (3 marks each)

Answer each question in 30-50 words. These questions require you to explain concepts, differentiate between terms, or perform simple calculations. CBSE Class 7 Science term exams typically allocate 2-3 marks for such questions, expecting clear definitions, correct formulas, and neat numerical work with units. Structure your answer in three parts: state the concept or formula, show the calculation or explanation, and write the final answer with the correct unit. For definitional questions, give examples from daily life as the NCERT textbook does. For numerical questions, always write the given data, formula, substitution, and final answer separately. Marks are often split: 1 mark for formula, 1 for substitution, 1 for correct answer and unit. Practising these short-answer questions builds the foundation for tackling long-answer and HOTS questions in Section E.

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

Answer each question in 80-120 words or solve the numerical problem showing all steps. These questions test higher-order thinking skills such as application, analysis, and evaluation. CBSE awards full marks only when you provide a well-structured answer with correct reasoning, diagrams where asked, and proper units in numerical questions. For graph-based questions, use a ruler and label axes clearly with quantity and unit. For numerical problems, write Given, To Find, Formula, Calculation, and Answer as separate subsections. HOTS questions often present unfamiliar scenarios; apply the concepts of speed, distance, time, and graph interpretation learned from NCERT Class 7 Science Chapter 9 to solve them. Spend about 6-7 minutes per question in this section. These questions closely mirror CBSE term-2 exam patterns and school pre-board papers.

Case Study Question (4 marks)

Read the passage carefully and answer the questions that follow. Case-study questions are part of the competency-based assessment framework introduced by CBSE from the 2023-24 session for Classes 6 to 10. They test your ability to apply theoretical knowledge to real-life situations, analyze data, and draw conclusions. The passage will describe a practical scenario involving motion, speed measurement, or time-keeping devices. Questions may be a mix of MCQ, one-word answers, or short explanations. Underline or highlight key data points in the passage such as distances, times, and speeds before attempting the questions. Cross-check that your answers are consistent with the information provided. Such questions have appeared in CBSE sample papers and are now a regular feature in school term exams for Class 7 Science.

Answer Key with Explanations

Below is the complete answer key for all sections of this CBSE Class 7 Science Chapter 9 Motion and Time worksheet. Each answer includes a brief explanation or working to help you understand the reasoning. If you scored below 60% (30 marks out of 50), revisit the relevant sections in your NCERT Class 7 Science textbook and class notes before attempting the worksheet again. For numericals, pay special attention to unit conversions and formula applications. If specific question types (like graph interpretation or HOTS) caused difficulty, practice similar questions from NCERT exemplar or reference books. Students aiming for above 90% should focus on speed and accuracy, ensuring zero marks are lost due to silly mistakes or incomplete units. Parents can use this answer key to provide immediate feedback and identify topics needing reinforcement.
