Answer :
Final answer:
In a bus, standing forward or sideways during acceleration and braking affects your body due to inertia. Sideways standing helps adjust to these forces due to friction and holding onto something for stability.
Explanation:
Standing on a bus when it accelerates or decelerates affects your body due to inertia. When the bus accelerates, if you're standing facing forward, your body tends to stay in place, causing you to move backward relative to the bus. If it brakes suddenly, you tend to move forward. Standing sideways allows your body to adjust more easily to these changes as you can use friction from holding onto something to counteract the forces.
