Why are road accidents at higher speeds more disastrous as compared to those at low speeds?

Higher speeds involve higher forces which do more damge in breaking bones, etc. Ther force is f=ma = mdv/dt, the higher the speed the greater the deceleration on impact thus causing greater force on structures. There is also higher energy in higher speeds.
At low speeds the energy and forces are smaller. The energy goes up by the speed squared, so twice the speed gives four times the energy. Twice the speed gives twice the force. The damage relates to the force the structures can take before damage.

What are the speeds of a long wave light compared to a short wave light?
Their speeds are exactly identical.
At higher speeds a vehicle's rate of acceleration will be?
There's no necessary connection between a vehicle's speed and its acceleration.
Do higher wind speeds increase air temperature?
They can bring warmer air, but typically they don't change it, and it feels colder.
Why are car crashes more dangerous at higher speeds than at lower speeds?
when your going fast you hit harder which causes more damage, but when your going slow you hit slower than you hit fast which cause less damage.
Why a high speed collision may cause more damage than a low speed collision?
At higher speeds, there is more kinetic energy involved.
Why are accidents at high speeds more fatal than accidents at low speed?
The higher the speed of a collision, the more energy it has, and the more damage it can do.
Why are accident at high speeds more fatal than accidents at low speed?
The higher the speed of a collision, the more energy it has, and the more damage it can do.
Why people die in road side accidents?
Because of high speeds.
What are the advantages of a Ferrari motorcycle compared to other motorcycles?
Some advantages of a Ferrari motorcycle compared to that of a regular motorcycle is that a Ferrari motorcycle can reach much higher top speeds while handling much better.

What are the speeds of a long wave light compared to a short wave light?
Their speeds are exactly identical.
Why car crashes more dangerous at higher speeds than at lower speed?
Higher g's produced at higher speeds are harder to survive.
Why are your RPMs high at high speeds?
Because your motor is spinning faster at higher speeds causing higher rpm's
Why are car crashes more dangerous at higher speeds than a lower speeds?
Because at higher speeds you have more velocity than at lower speeds transferring more energy to make a bigger crashing causing more damage.
How many people die in motorcycle accidents?
most of them well most of them die because of not wearing helmets so be safe and wear your helmetsIn the UK there are tight safety regualtions as to the protective gear a motorcyclist should wear whilst on a public highway. This gear does mean that the majority of accidents result in minor injuries.But, when large speeds are involved or head collisions regretfully motor bike accidents can be very serious and can cause fatalities. As a percentage of the number of overall motorcycle accidents the fatality ratio is low, but compared to the percentage fatalities in car accidents it is comparatively high.
What is the difference between a bicycle helmet and a moped helmet?
A moped helmet is sturdier, heavier and less ventilated. It is expected to provide decent protection at accidents at higher speeds than a bicycle helmet. A bicycle helmet is lighter, better ventilated and only has to provide decent protection at lower speeds than a moped helmet.
Why are road accidents at high speed very much worse than accidents at low speeds?
This is because the momentum of high speed vechicle is more than that of the low speed vechicle
