Step 2 (15 minutes)

Idea about impulse and impulsive forces.

Restructuring of idea

Activity: Discussion with group about impulse and the impulsive forces. Question 1 What an impulse? Question 2 What an impulsive forces. Question 3 How increasing or decreasing time of impact affects the magnitude of the impulsive forces.

objective of learning for today’s lesson.

3. Teacher shows a picture and asks what happen to the car if with increasing or decreasing time.

3. Students give their answer.

4. Teacher view computer of simulation and explosions to gain an idea on impulsive forces. 1. Teacher divides the students into 4 in a group. Then, teacher gives a number to each student. 2. Teacher asks to student what an impulse? 3. Teacher asks to student what an impulsive forces. 4. Teacher ask how increasing time of impact affects the magnitude of the impulsive forces.
