As inertia is a tendency to do nothing, not wearing a seat belt (in a stationary vehicle?) will have little affect. Only if the vehicle is moving and suddenly stop, does wearing a seat belt become essential.
inertia (=
In physics, inertia means that though the car is brought to a sudden stop, the person inside will continue in a forward motion. A seat belt would restrain the person's forward movement and prevent the person being injured by the dashboard, or by being thrown through the windscreen. Air-bags are used in modern cars to also cushion against the effect of inertia.
Inertia
Yes, wearing a seat belt in a car is important because of inertia. Inertia is the tendency of objects to resist changes in their motion, so when a car stops suddenly, your body continues to move forward due to inertia. A seat belt helps to restrain your body and prevent serious injuries in the event of a sudden stop or collision.
Inertia=An object in motion tends to stay in motion until it is acted upon by an outside force
The person not wearing the seatbelt is the only one who risks getting harmed.
No. A seat-belt is not inertia. But if you are trying to ask if a seat-belt does anything with inertia, then yes. An example is, You are riding in a car at a high speed. Then out of no where, you see a red light. You slam on your breaks and jolt forward. your seat-belt helps you resist inertia by holding you back so you dont fly out the window. If you hadn't been wearing your seat-belt and have been riding at a high enough speed, and hit your breaks hard enough, you would fly out the window and crack your head open. So yes, a seat belt protects you from inertia. But, inertia can be good in some other cases that I wont get into. Remember Newton's first law of motion has to do with inertia. The short version of the law is, An object in motion wants to stay in motion, while an object at rest wants to stay at rest. If this helps at all, let me know on my message board. Thanks!
because you should excert the dummy
If there is no seat belt fitted to the vehicle, then possibly. If theres a seatbelt fitted and its not used, then likely no.
Inertia is the tendency of an object to resist changes in its state of motion. When a car suddenly stops, your body continues moving forward at the same speed due to inertia. Wearing a seat belt helps counteract this effect by securely holding you in place, preventing you from being thrown forward and reducing the risk of injury during a collision or abrupt stop.
What is Brian wearing on his BELT in Hatchet chapter 1
Inertia. You want to go straight, the car (door) [you should be wearing seat belt] is forcing you to curve.
