9 (a) Diagram 9.1 represents a 50 sen coin and a leaf falling in a vacuum container.

The coin is heavier than the leaf.

Rajah 9.1 mewakili sekeping duit syiling 50 sen dan sehelai daun jatuh di dalam sebuah

bekas vakum. Duit syiling adalah lebih berat dari daun.

Diagram 9.1 Rajah 9.1

Using Diagram 9.1 and the information given about the weight of the two

objects, compare the mass of the coin and the leaf, the time taken to fall, the

positions of the coin and the leaf and finally, deduce the physical quantity

which causes the objects to fall.

Dengan menggunakan Rajah 9.1 dan maklumat yang diberikan mengenai berat objek,
