![]() ![]() The program works only with the following simple two-dimensional motion equations: d=vt+1/2at^2 V^2=v^2+2ad V=v+at where each variable has the following assignments: d = distance v (lowercase) = initial velocity V (uppercase) = final velocity a = acceleration t = time These equations can also be applied to rotational motion as the equations used in that field are identical, except for different variables therefore, the program serves a dual purpose. It reduces calculation time by simply asking the user for the known values and then solving for the unknown value. Up to TI-83/84 Plus BASIC Science ProgramsĢD Motion Master is basically a plug and chug program.

TI-83/84 PLUS BASIC SCIENCE PROGRAMS (OTHER PHYSICS) TI-83/84 Plus BASIC Science Programs (Other Physics) In the following diagram you can find the distances h and l which are required for the calculation of the overturn of a vehicle.TI-83/84 Plus BASIC Science Programs (Other Physics). The total time for braking is made up of reaction time and braking time. Overall stopping distance is the sum of braking distance and thinking distance. Formulas for Speed, Acceleration, Time & Distance.So the car hits the obstacle at full speed! In this case reaction distance is already greater than the total stopping distance from 1). The difference between the two numbers gives the reaction distance: 27.778 m. The total stopping distance is 38.701 m, the braking distance is 10.923 m. As „Reaction time“ choose 2 and replace the „Initial speed“ by a value of 50. Under these conditions, the car is still about 42 km/h fast!įirst reset the calculator. Let all the other values as they are – then select „Dry roadway“. The result is 33 km/h.įor this calculation, you have to put in the value 50 in the „starting velocity“ field. First, change the condition to „Wet roadway“ (click on the small arrow). If you want to find out the collision speed, the braking distance calculator must be filled out as shown in the screenshot below:Īfter entering the values, do not press the „Calculate“ button immediately. For the correct answer, of course, the stopping distance has to be taken. To be able stopping just in time, the car must be 24.812 m away from the child. In the „starting velocity“ field, you have to put in the value 50 instead of 100. The car’s initial velocity is 50 km/h, a reaction time of two seconds is assumed. What stopping distance does the vehicle have?.What’s the car’s speed when it is hitting the child? The stopping distance should be the same as in 1). The driver runs illegally at 60 km/h through the village.Now the road is wet. What’s the car’s speed at time of the accident?.How far away from the child does the car have to be so that it can stop just in time? A reaction time of one second is assumed. ![]() Obstacles – Effect of Speed or Reaction TimeĪ vehicle travels on a dry and even road through a village. Accuracy can not be guaranteed – for corrections or additions please use my contact form!.It is assumed that all the wheels are braked or driven.In curves, there is less acceleration or deceleration possible.The calculation is only valid for uniform acceleration or constant deceleration.Stopping (Braking) distance or acceleration distance.Depending on the road or rail conditions, the two calculators compute the following:.Reference Values for Acceleration or Deceleration.Obstacles – Effect of Speed or Reaction Time.Examples for the Use of these Calculators. ![]()
