From there, calculating the force of an impact is relatively easy. To put it in its simplest terms, impact force is the force created when two or more things collide. Dropped Objects: Risk Awareness and Prevention - Ergodyne PDF Acceleration Levels of Dropped Objects - Endevco Calculating the force in a wide range of situations is crucial to physics. The DROPS Calculator provides a common benchmark in the classification of the potential consequences of a dropped object. Sometimes this is called the "deformation slow down distance," and you can use this when the object deforms and comes to a stop, even if it doesn't penetrate into the ground. Working at height poses a series of unique risks to the workplace. Attachment points function similarly to a workers safety harness in that it must be a secure point on the tool that is load-rated for at least the total weight of the tool.
