The lesson plan is a very important tool for teaching. Today we are going to discuss the lesson plan on **Motion: Acceleration**

## Lesson plan on Motion: Speed and Velocity

Name of the Teacher: XXRoll No: 00Class: IXThe average age of the students: 14 + years | Subject: Physical ScienceLesson Whole: MotionLesson Unit: Speed & VelocityDuration: 40 MinutesDate: DD/MM/YY |

#### General Aims

- To create interest in the students to study the subject Physical Science
- To develop a scientific attitude among the students

#### Specific Objective

- To enable the students to recall the term acceleration
- To enable the students to differentiate between uniform and non-uniform acceleration

#### Teaching Aids

Blackboard, chalk, duster, chart, and pointer

### Step-I Preparation

**Motivation**: In order to motivate the students the following questions will be asked

Questions | Expected Answer |

1. when a train starts moving from a platform, what does its speed increase or decrease | Increase |

2. what happens when an airplane land at the airport | speed decrease gradually |

3. A cyclist moving through a busy street, when his velocity increase, what does it call? | He is said to acceleration |

4. what does it call when the cyclist’s speed decreased | De-acceleration or retarding |

#### Announcement

So class, today we are going to learn about “Acceleration”

## Step-II Presentation

Teaching Points | Instructional Objectives | Teaching Methods | Teacher’s activity/ Discussion | Blackboard work | Testing-Learning outcomes | Learning Outcomes |

1. Acceleration | Students are able to define acceleration | Lecture Method | The rate of change of velocity of a body with respect to time is called its acceleration | Acceleration: Change in velocity/Time taken to change=Final velocity-Initial Velocity/Time taken to change =v-u/t where Time=t, Initial velocity=u, Final velocity=v, acceleration=a | 1. Define Acceleration. write down the formula of acceleration | students are able to define acceleration |

2. units of acceleration | Students are able to identify the SI unit | Lecture method | The SI unit of acceleration is Meter per second square | SI unit of acceleration is m/s-2 | 2. write down the SI unit of acceleration | Students learns the SI unit of acceleration. |

3. Uniform acceleration | students able to recognize the uniform acceleration | Lecture and Discussion Method | When a body undergoes equal changes in velocit in equal intervals of time, the body is said to be moving with uniform acceleration Ex. A freely falling body under the pull of Earth | -It is an equal change in velocity in an equal interval of time | 3. what is uniform acceleration? | students able to define uniform acceleration |

4. Non-Uniform or Variable acceleration | Students able to differentiate between uniform and non-uniform acceleration | Lecture cum Discussion Method | When a body undergoes unequal changes in velocity in equal intervals of time, the body is said to be in non-uniform motion. Ex. when a car push breaks frequently on a crowded road | A body is said to have non-uniform acceleration when it undergoes unequal changes of velocity | 4. Define variable acceleration | students able to differentiate between uniform and non-uniform acceleration |

5. Definition of Retardation | Students are able to recall the term retardation | Lecture method | If the velocity of a body decrease then the rate of change of velocity is negative and it is called retardation. In this case final velocity of the body is lesser than the initial velocity | Final Velocity is lesser then the Initial velocity Retardation=v<u | 5. What is retardation? | students learn about retardation |

### Step-III Recapitulation

In order to test the pupil’s understanding of the lesson just taught, the following question will be asked

- Define the term acceleration
- What is the SI unit of acceleration
- What is called retardation?
- What do you mean by uniform acceleration?
- What is non-uniform acceleration?

### Step-IV Remedial Teaching

Remedial teaching will be done if found necessary

### Step-V Home Assignment

The following questions will be given for homework

- Distinguish between acceleration and Retardation
- What is acceleration? Give example
- what is variable acceleration. Give example

**Conclusion:** Well class, Today we have learned about “Acceleration”. In the next class, we will learn about “Force”.
