There are 10 cars in a row, all moving in the the same direction with the same speed.
You are the driver of the second car.
You reaction time will determine if an accident will happen or not.
(and how many cars will be involved in the incident)
The graph show the velocity for all the cars.
If the car turn red, you know what happened to it.
Hi
I have only just found your wonderful web-site & have tried the
accident
experiment, it really is a good lesson for us drivers.Perhaps it should
be
included in driving tests.
I had not appreciated the "knock on" effect until I noticed that although
I could stop in time those behind me could not.
I found that at 100 mph I had to allow 75 feet between cars for them
all
to stop & even then it was not succesful every time. A wet
road would of
made it much worse.
Thanks for a very interesting site, although I have no formal education
in
Physics I find it fascinating, so I am going to try the other experiments
now.
