Presentation (प्रस्तुतीकरण):-

---------

Teaching Points	Teacher Activity	Student Activity	Blackboard Activity	Expected Learning Outcome
Introduce with motion along a straight line	Explain straight line motion with simple example	Listen and observe examples	Motion: change in position over time	Students understand the concept of motion.
Example of Straight Line Motion	Explain with example: a car moving on a straight road	Observe example; relate to personal experiences	Example: Car on straight road	Visualize real-life motion along a straight path
Analogy: Train Moving Along Tracks	Compare with a train moving along straight tracks	Think of examples of motion in straight paths	Analogy: Train on a straight track	Relate straight-line motion to everyday situations
Real-Life Application: Running on a Track	Use analogy of runner moving in a straight path on a track	Discuss examples; relate to own activities	Runner moving in a straight line	Apply straight-line motion concept in daily life

Encapsulation (पुनरावृत्ति):-

Motion along a straight line is the simplest form of motion, making it essential to understanding basic kinematic concepts. It allows students to differentiate between fundamental terms such as distance and displacement and introduces them to speed and velocity as measures of motion.

Homework (गृहकार्य):-

• Define distance, displacement, speed, and velocity with examples.
• Practice problems: Calculate distance and displacement for given paths.
• Draw a distance-time graph for uniform and non-uniform motion.
. 

Other Points (अन्य बिंदु):-

Motion in a straight line simplifies calculations.

Distance is scalar; displacement is vector (includes direction).

Speed differs from velocity as speed doesn’t consider direction.
