2. Introduction 3. What causes the car to be bumped whenthere are collision occurred between the carand an object? 4. Impulsive force is the enormous amount offorce acting for a very small time on a bodymv-muF =t 5. For 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. 6. The karate expert hitsthe stone swiftly .Therefore, force isbigger. 7. Problem Statement 8. What are the factors that influencethe amount of Impulsive Force ? SpeedTimeMass 9. When an object crushes on a hard surfacewill cause a large impulsive force Egg EggSponge 10. Why the athletic needed to bend theirleg while making a long jump or a highjump? 11. What will happen if withoutapplying the knowledge ofImpulsive Force? 12. Arghh!! 13. ObjectiveTo help people realize the importance ofImpulsive Force in daily life General Objective:- To determine whether the different surfacewill affect the impulsive force- The effect of increasing or decreasing oftime of impact on impulsive force 14. - To determine whether the velocity willaffect the impulsive force- To determine whether the different mass ofobject will affect the impulsive force 15. Do you think that impulsive forceimportant in saving life? 16. Conclusion of the Result of Questionnaire 17. Do 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. 18.

Apparatus & Materials are prepared for conducting experiment. 21. Members are setting up the sponge for preparation of experiment. 22. Members are preparing the scale diagram for calculating the displacement of the sponge after collide by egg 23. The scale diagram & sponge are done prepared. 24. Members are measuring the distance 2 meters for carrying experiment. 25. The distance 2 meters is done measured 26. Members are discussing how to conduct the experiment. 27. The reading of displacement of the sponge is taken & recorded. 28. AcknowledgementSchool principal, Pn. Balkhis Binti Abdul RahimTeacher in charge of RC project En. SritharanRC Physics tutor Pn.
