This document discusses impulsive force and presents a student project on the topic. The project aims to determine how factors like surface, impact time, velocity, and mass affect impulsive force. It outlines objectives, experiments, and findings. The group measured displacement of an egg and sponge to study impulsive force. They found most teachers and students were unaware of impulsive force, showing its importance. The document provides context, methodology, results, and acknowledgments for the student project on this physics concept.

2. Introduction

3.  What causes the car to be bumped when
there are collision occurred between the car
and an object?

4.  Impulsive force is the enormous amount of
force acting for a very small time on a body
mv-mu
F =
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 hits
the stone swiftly .
Therefore, force is
bigger.

7. Problem Statement

8.  What are the factors that influence
the amount of Impulsive Force ?
Speed Time Mass

9. When an object crushes on a hard surface
will cause a large impulsive force？
Egg Egg
Sponge

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

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

12. Arghh!!

13. 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

14. - To determine whether the velocity will
affect the impulsive force
- To determine whether the different mass of
object will affect the impulsive force

18. Do you think that impulsive force
important in saving life?

19. Conclusion of the Result
of Questionnaire

20. Do anyone know what is
impulsive force?
 About 60% of teachers don’t know
 About 70% of students don’t know
 So, overall 65% don’t know it actually.

23. Apparatus & Materials are prepared for conducting experiment.

24. Members are setting up the sponge for preparation of experiment.

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

26. The scale diagram & sponge are done prepared.

27. Members are measuring the distance 2 meters for carrying experiment.

28. The distance 2 meters is done measured

29. Members are discussing how to conduct the experiment.

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