Working out the impact force when the object bounces afterward is a lot more difficult. See our full terms of service. Identifying a dropped object hazard can be as simple as noticing a small tool or pile of screws laying near an at-height edgeany of which could be accidentally kicked or blown by the wind, falling to a lower level. During a collision like this, kinetic energy transfers from one object to another. Impact Force from Falling Object Even though the application of conservation of energy to a falling object allows us to predict its impact velocity and kinetic energy, we cannot predict its impact force without knowing how far it travels after impact. 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 doesnt penetrate into the ground. You can estimate this to come up with an answer, but there are some situations where you can put together a firmer figure. You can work this out easily for any object that falls as long as you know how big it is and how high it falls from. Calling the distance traveled after impact d, and noting that the change in kinetic energy is the same as the gravitational potential energy, the complete formula can be expressed as: The hardest part to work out when you calculate falling object forces is the distance traveled.
