When an explosive adjacent to a layer of a metallic or other solid material detonates, the layer is accelerated both by the initial detonation shock wave and by the pressure of the detonation gas products. All of the equations derived based on Gurney's methods are collectively called "Gurney equations". Other researchers have extended similar methods of analysis to other geometries. The original paper by Gurney analyzed the situation of an exploding shell or bomb, a mass of explosives surrounded by a solid shell. The equations were first developed in the 1940s by Ronald Gurney Īnd have been expanded on and added to significantly since that time. This determines how fast fragments are released by military explosives, how quickly shaped charge explosives accelerate their liners inwards, and in other calculations such as explosive welding where explosives force two metal sheets together and bond them. It does not store any personal data.The Gurney equations are a set of mathematical formulas used in explosives engineering to relate how fast an explosive will accelerate an adjacent layer of metal or other material when the explosive detonates.

The final speed of an object is the same as the initial speed of that object and the time it takes for the object to travel from one point to another. The difference between speed and velocity is referred to as a scalar value. The time rate at which an object is moving is known as speed, while the direction of the object’s movement is known as velocity. What is velocity in physics?Īs an indication of the rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time,velocity is the speed at which an object moves. The units for speed are meters per second. There is a magnitude as well as a direction in the shape of the figure. The change in the position of an object is divided by time. The wave’s velocity can be calculated using the equation v-f v-f.Ī measure of how fast an object moves is known as vechicle. The first step is to figure out the wave’s frequencies and wavelength. The equation v is represented by the equation s/t, which is a measure of displacement over time. The equation V is the speed, the distance and the time. If you divide the time it took for the object to travel by the total distance, you can figure out the object’s original velocity.
