IMPULSIVE FORCECREATED BYSURAYA BT SHABINGIN

1Introduction2What causes the car to be bumped when there are collision occurred between the car and an object?

3Impulsive force is the enormous amount of force acting for a very small time on a bodymv-mu tF=4For example ,A karate expert can break thick wooden slab with his bare hand that moves at a very fast speed. The short impact time results in a large impulsive force on the wooden slab.5

The karate expert hits the stone swiftly . Therefore, force is bigger.6Problem Statement7 What are the factors that influence the amount of Impulsive Force ?

Time

Mass

Speed8When an object crushes on a hard surface will cause a large impulsive forceStoneSpongeEggEgg

9 Why the athletic needed to bend their leg while making a long jump or a high jump?

10What will happen if without applying the knowledge of Impulsive Force?

Arghh!! Objective

To help people realize the importance of Impulsive Force in daily life

General Objective:- To determine whether the different surface will affect the impulsive force

- The effect of increasing or decreasing of time of impact on impulsive force

13- To determine whether the velocity will affect the impulsive force

- To determine whether the different mass of object will affect the impulsive force14

Do you think that impulsive force important in saving life?

Conclusion of the Result of Questionnaire19Do anyone know what is impulsive force?

About 60% of teachers dont know About 70% of students dont know

So, overall 65% dont know it actually.BibliographyBook Reference:Physics Reference Book (Ace Ahead) Volume 1 written by Poh Liong Yong, Jonathan Wong, Lee Beng Hin 2008Physics Reference Book (Pearson Longman) Volume 1 written by Cheong Foon ChoongPhysics Reference Book (Pelangi) Volume 1 written by Poh Liong YongA college text-book of physics written by Arthur Lalanne Kimball and Peter Irving Wold Mechanics for Engineering written by H.

Apparatus & Materials are prepared for conducting experiment.

Members are setting up the sponge for preparation of experiment.

Members are preparing the scale diagram for calculating the displacement of the sponge after collide by egg

The scale diagram & sponge are done prepared.

Members are measuring the distance 2 meters for carrying experiment.

The distance 2 meters is done measured

Members are discussing how to conduct the experiment.

The reading of displacement of the sponge is taken & recorded. Acknowledgement
