有關inertia既問題..

Question

相撲係日本傳統既運動, 一個相撲手要羸就要將對方推出圈外. d相撲手重135kg至180kg..
試講述點解相撲手要咁有份量(why Sumo wrestlers need to be so 'massive'.)

如果有一件物件只有一種力用於其上(only one force acting on an object), 請問那件物件可否擁有0加速度(can the oject have zero acceleration)? 請詳細說明

p.s..用英交答"

Answer 1

1. Greater mass implies greater inertia. A larger force is needed to overcome the inertia of a massive wrestler, thus helping the wrestler to gain stability.

2. If there is only a single force acting on the body, it would have an acceleration.
