Situation :

Observe the situation above. The picture show Abu and Bakar pushing two trolley. Abu seems to have more difficulty pushing the trolley than Bakar.

Using the information :

(a) Make a suitable inference

(b) State a suitable hypothesis that can be studied

Using proper apparatus such as inertial balance, three cylindrical masses, G clamp and stop watch.

(c) Elaborate one experiment to test your hypothesis. Include the information below in your report :

i. Purpose of experiment

ii. Variable exist in the experiment

iii. List of apparatus

iv. Apparatus arrangement

v. Procedures to control manipulated variable and responding variable.

vi. Method of tabulating data and analyzing data

vii. Using the procedures run a experiment and make a analysis and

conclusion.
