PULL UP VS FRICTION

Learning Outcomes

1.       STUDENTS WILL BE ABLE TO UNDERSTAND THAT MORE THE ROUGHTNESS OF THE SURFACES MORE IS THE FRICTION AT THE END OF THIS ACTIVITY.

2.       STUDENTS WILL BE ABLE TO UNDERSTAND THAT MORE IS THE LOAD MORE IS THE FRICITON AT END OF THIS CHAPTER.

3.       STUDENTS WILL BE DEVELOP MUSCLE STRENGHT AFTER PERFORMING THIS ACTIVITY.

4.       STUDENTS WILL DEVELOP COLLABORATION, TEAM SPIRIT, AND SOCIAL HARMONY AT THE END OF THIS ACTIVITY.

Description Of Activity

1.       STUDENTS WILL BE TAKEN TO THE GROUND WHERE THE ARRANGEMENT OF BARS TO PULL UP IS MADE.

2.       STUDENTS WILL BE MADE INTO 8 GROUPS ACCORDING TO SAME WEIGHT, HEIGHT AND GENDER.

3.       THERE WILL BE TWO BARS, ONE WILL BE OILED ANOTHER WILL BE ADDED SOME COARSE (ROUGH) POWDER.

4.       EVERY STUDENTS IN EACH GROUP WILL BE ALLOWED TO PULL UP IN THE OILED BAR AND COARSE POWDERED BAR FOR 30 SECOND AND NUMBER UP PULL UP WILL BE RECORDED IN THE TABLE.

5.       IN THE SECOND ROUND ALL THE STUDENTS WILL BE ASKED TO HOLD THE SCHOOL BAG IN THE SHOULDER WITH SAME NUMBER OF BOOKS IN THE BAG AND RPEAT THE SAME PULL UP EXCERXISE AND THE NUMBER OF PULL UP WILL BE RECOREDED IN THE GIVEN TABLE

6.       BY COMPARING THE TABLE CONCLUSION CAN BE DONE THAT THE NUMBER OF PULL UP FOR SAME STUDENT IN THE COARSE POWDERED BAR WILL BE MORE THAN OILDED BAR. WHICH INDICATES THAT FRICTION INCREASES WHEN ROUGHNESS OF THE SURFACE IS INCREASED,

Variations

CARROM MATCH WITH AND WITHOUT CARROM POWDER CAN BE A BETTER OPTION TO UNDERSTAND THE CONCEPT. CYCLING RACE IN PLAIN GROUND AND UNEVEN GROUND CAN ALSO BE ANOTHER OPTION TO UNDERSTAND THIS CONCEPT.
