Planning an effective lesson plan for uniform and non-uniform motion is crucial for Class 9 science educators aiming to deliver conceptually strong and engaging physics instruction. The Motion chapter in Class 9 NCERT Physics introduces foundational kinematic concepts that serve as the building blocks for higher-level physics topics.
As such, a well-structured pedagogical approach is essential to help students distinguish between uniform motion and non-uniform motion, understand their graphical representations, and apply real-world examples effectively.
Introduction
This blog post provides a detailed and curriculum-aligned lesson plan designed specifically for Class 9 CBSE Physics teachers, incorporating teaching strategies, learning outcomes, interactive classroom activities, and assessment methods. The goal is to foster conceptual clarity, enhance student participation, and ensure smooth progression through the motion chapter of NCERT Class 9 Science.
Whether you are a new teacher, a seasoned educator seeking refinements, or a curriculum planner, this guide will support your efforts in delivering quality science education while aligning with NCERT learning outcomes and CBSE board standards.

Introductory Questions
| Introductory Questions | Expected Answer |
|---|---|
| What do we mean by motion? | When an object changes its position with time. |
| Can you name some moving things around you? | Cars, people, birds, fans, buses. |
| Is a car moving at constant speed always uniform motion? | Only if it covers equal distances in equal time intervals. |
| Do all objects move in the same way? | No, some move at constant speed, others change speed. |
| How do we measure how far something moved? | Using a measuring tape or meter scale for distance. |
| What is time and how do we measure it? | Time is a measure of duration, measured with a clock or stopwatch. |
| If a car moves faster than a bicycle, what does it indicate? | It covers more distance in less time – it has higher speed. |
Lesson Plan
| Teaching Point | Teacher Activity | Student Activity | Blackboard work | Evaluation |
|---|---|---|---|---|
| 1. Definition of Motion | Explains motion as change in position with time. | Listen and observe surrounding examples. | Write: “Motion = Change in position with time” | Write: “Motion = Change in position with time” |
| 2. Uniform Motion | Describes motion of a car at constant speed on highway. | Note down definition and example. | “Uniform Motion = Equal distance in equal intervals” | Ask: Give a real-life example of uniform motion. |
| 3. Non-Uniform Motion | Shows a video clip of traffic jam movement. | Compare with uniform motion, discuss changes in speed. | “Non-Uniform = Unequal distances in equal intervals” | Think-pair-share: Why is traffic motion non-uniform? |
| 4. Speed vs Time Concept | Uses stopwatch to measure student walking across classroom. | Participate and measure own walking time. | Draw sample distance-time table for two students. | Q: Who had uniform motion based on the data? |
| 5. Graphical Understanding (Intro only) | Shows distance-time graph with straight and curved lines. | Identify which is uniform and which is non-uniform. | Sketch 2 graphs: 1 straight, 1 curved line | Q: What does a straight line graph indicate? |
Homework
- Define uniform motion with an example from daily life.
- Why is walking in a park considered non-uniform motion?
- A bus travels 10 km in each of the first two hours and 5 km in the next hour. Is it uniform motion? Explain.
- Draw a distance-time graph for an object in uniform motion.
- If an athlete covers different distances in each second, what type of motion is it?
- List 3 occupations where understanding types of motion is essential.
Encapsulation
