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.Some Notes for the Use of the Calculator (manual).*** The meaning of the two abbreviations l and h can be found here: General Information. The stopping capacity/braking capacity of the vehicle, that is, how fast the vehicle can decelerate.Īt the stopping point, the vehicle has applied the brakes, and now it has to come to a stop.* Change the rail or road condition in the first calculator assumption: all wheels are braked.Imagine the same scenario as before, people driving/riding a vehicle and an object coming in front, after analyzing that brakes are needed to be applied, when the brakes are actually applied, it takes a certain time for the vehicle to come to rest, the distance covered in that time is Stopping Distance. When an object moves with a certain velocity and breaks are applied, the object takes some time to come to a stop, it is obvious that at this time, the object must have covered a certain distance, this distance is known as the Stopping distance. The situations/surroundings in which the reaction time is taking place.It is due to the fact that the friend is not aware of the time of the drop of a pen, hence, when the pen is dropped, he may take some time to respond to that, this is nothing but reaction time taken by the friend. Imagine holding a pen in hand at a certain height and asking a friend to instantly catch the pen as soon as it is dropped, it is obvious that the pen will fall a little before the friend can catch it. Not only on road, normally reaction time can be analyzed too. When people drive/ride their vehicle on the road, and suddenly an object comes in front of the road, now in order to stop the vehicle, the brain first has to acknowledge the hurdle on the way and warn the body to respond to the danger, the time taken to do this process is nothing but Reaction time. Reaction time can be defined as the time taken by a human to react or respond to a sudden change or stimulus. Let’s learn about these two topics in more detail, Reaction Time Some very interesting concepts to see in Non-uniform motion are Stopping distance and Reaction time. Third Equation of motion ⇢ v 2 = u 2 + 2as Second Equation of motion ⇢ S = ut + 1/2(at 2) When some external force is applied to the object and the object gains motion, it starts to move, if the motion occurs in one direction, it is known as rectilinear motion. When the object has no kinetic energy and no external force is applied on the object, it remains at rest. This type of motion is also known as Rectilinear motion. Motion in one direction or motion in 1-dimension is the motion in a straight line. Let’s learn about the Motion in a straight line in more detail, Motion in a Straight Line The motion of a body is observed w.r.t a frame of reference, on a graph, the origin is denoted as the frame of reference. One dimensional motion is the object moving in a straight line, two-dimensional motion is when an object moves covering two axes (x-y, y-z, z-x axis), three-dimensional motion is when an object moves in all three x-y-z directions. There are three types of motion possible, one dimensional, two-dimensional, and three-dimensional motion. When an object gains kinetic energy and changes position, it is known to be in motion.
