Question

UUUUU
3. "Wearing helmet and fastening the seat belt
is highly recommended for safe journey"
Justify your answer using Newton's laws of
motion.​

Answer 1

Answer:

This is recommended due to Newton 1 law of motion or Law of inertia in which a body tends to be at a same position after being in motion .

So if we wear helmets then if the vehicle starts our body will want to be in rest so it will fall backward and if comes to rest our body will fall in forward direction so to prevent ourselves from getting hurt we use helmets or seat belts which don't let us fall .

Answer 2

Explanation:

• According to newton's second law, when you fall from a bike on the ground with a force equal to your mass and acceleration of. the bike.
•  According to newton's third law, an equal and opposite reaching force on the ground is exerted

on you.

•  When you do not wear helmet, this reacting force can cause fatal head injuries. So it is

important to wear helmet for. the safe journey.
