As I recall high school physics, force increases with the square of velocity.

Energy = 1/2 mass * velocity (squared)

Force = mass * acceleration

"force increases with the square of velocity."

E = 1/2 *m*v2

F = m * a

where a = acceleration = dv/dt.

nope ...

Where m is the inertial mass of the velocity, and T is the time from the initial state to the final state; the expression on the right of the equation being the limit as T goes to zero.

I think you are thinking about Kinetic Energy, which is a bit different. particle, vo is its initial velocity, v is its final That formula is probably what you meant, and that is given as:

.

So, yes, the faster you go, the harder you hit. Having a heavy car means that you hit harder; although the heavy car can absorb the impact by deformation (hopefully in a manner that protects the occupants).

Energy, too.

The primary cause of accidents on the highways in the western US is drivers dozing off. This used to be called highway hypnosis. States found that by increasing speed limits, drivers were less likely to doze off on long trips.

They abondoned highway hypnosis when trial lawyers complained that juries were reluctant to award damages against drivers who fell asleep at the wheel as opposed to violating a traffic law.

Insurance companies like to use highway death statistics to show that lower speeds and safer cars lower highway deaths.

The lower death rates they champion are directly attributable to the Viet Nam war, not lower speed limits or safer cars.
