## A.V aids :

Text book, black board, chalk, duster, charts, flash card

## Teaching method:

Lecture cum-inductive / deductive method

## Previous knowledge :

In order to check previous knowledge of students, teacher will ask questions such as,

1.when you roll a ball on ground why do it stop after traveling some distance.

2.When you play tug of war who wins and why?

## Announcing the topic :

Dear students, Today we are going to learn about “force”

## Presentation:

teacher Will define force: The push or pull on an object with mass that causes it to change its velocity. ∆ force is an external agent capable of changing the state of rest or motion of a particular body. Unit of force: The Force can be measured using a spring balance. The SI unit of force is Newton “N”. Equation of force: Equation for Force The quantity of force is expressed by the vector product of mass m and acceleration a. The equation or the formula for force can mathematically be expressed in the form of: F = ma Where, M = mass A = acceleration Effect of force .

The Force has different effects and here are some of them. Can make a body that is at rest to move. It can stop a moving body or slow it down. It can accelerate the speed of a moving body. It can also change the direction of a moving body along with its shape and size. Types of force Force is a physical cause that can change the state of motion or the dimensions of an object. There are two types of forces based on their applications: Contact Force Non-Contact Force

## Summative evaluation:

Tell me name of contact force Tell me name of non-contact force Homework: Write definition of force Write unit of force Write effect of force
