How to Use Stop-Explosion Calculator
Use Stop-Explosion Calculator by entering initial speed, available deceleration, and the explosion radius. The calculator first computes how far the moving object needs to stop, then adds that distance to the specified blast radius.
The deceleration value must be positive. If you are uncertain about braking or stopping capability, enter a conservative lower deceleration; lower deceleration produces a longer stopping distance and a larger safe distance.
Formula & Theory - Stop-Explosion Calculator
The core calculation is:
Stopping distance: d = v² / (2a)
Safe distance: r_safe = r_explosion + dThe stopping-distance equation assumes constant deceleration in a straight line. It comes from kinematics, where final velocity is zero and distance is solved from the initial velocity and deceleration.
The safe-distance equation is additive: it treats the blast radius and stopping distance as two separate margins. Real safety planning requires larger margins when terrain, reaction time, debris, blast wave behavior, or uncertainty is present.
Use Cases for Stop-Explosion Calculator
Use it for classroom physics demonstrations, safety training examples, robotics stop-zone sketches, or scenario planning where a moving object must stop outside a hazard radius.
It is also helpful for explaining why speed has a squared effect: doubling speed makes stopping distance four times larger when deceleration stays the same.
