Ch2 -Motion

   Classs-7 

Subject- Physics 

Chapter-2 Motion

No. Of periods required- 8

Topics :-1. Motion is relative

                2. Types of motion

                3. Simple pendulum

                4. Speed and velocity

               5. Uniform and non uniform motion 

Procedure:-

 I) Introduction- Chapter Motion will get introduced by talking about students ' position w.r.t me and black board.

Ii) Pre Knowledge- Students have learnt effects of force as brings moving object to rest and also moves object which is at rest.

III) Activity/ details

1. Terms rest and motion willl be explained by taking examples from day to day life.Also they are relative terms by taking example of position of passenger w.rt another passenger sitting next to him and w.r.t platform.

2.Objects can move in many different ways.Some of objects in sort of pattern called regular motion whereas motion of some objects donot have any patern called Regular motion.

Different types of regular motion will be explained by taking examples from day to day life

Types of motion

I) Translatory motion - * Rectilinear motion and Curvilinear motion

ii)Rotatory motion

iii) . Oscillatory motion

iv). Circular motion

v). Periodic motion

Activity1 - on mixed motion

A Ferris wheel ( model used)  rotates but it's cars are in circular motion

Motion of wheel of car Toy car used) - rotates as well as translatory motion.

3. Simple pendulum - This topic will be explained by conducting following Activity 2 

.To find time period of a simple pendulum  

4.Speed and velocity 

When we talk about motion of an object, we talk about it in terms of fastness and slowness.

There students will know about speed and velocity. and also difference between them.

They will also know about distance and displacement.

Activity 3 :-  To find distance and displacement

5. Uniform and non uniform motion 

Uniform motion - speed as well as direction remain constant if either of these changes - non uniform motion.

Examples from day to day life will be used to explain the above.

6. Chapter will be reviewed by using rainbow mindmap -
