Context You are consulted by a construction company to determine the speed at which a tool dropped from a certain height would hit the ground. Constraints We neglect the air resistance to be certain that the speed at which the tool would actually hit the ground is lower than the one we are going to calculate; The tool is not thrown up or down, it is simply dropped. Modelization Build a model to calculate the ground impact velocity modulus of a dropped tool as a function of the height from which it was dropped. Then test your model with the following value: Height at which the tool is dropped = 22.8 m

Mechanical Properties of Solids

There are three types of matter- solid, liquid and gas. Out of them, solids have a rigid shaped and size. The intermolecular forces of attractions in solids are greatest. Mechanical properties are the physical properties of a material which it shows, when it is provided with certain amount of force or load. These properties are to be kept in mind for various purposes. When a force is applied to an object, the object may or may not get deformed depending upon its elastic property. But every time the object develops a restoring force against the force applied. This is commonly known as stress. If the object changes its dimensions due to the force applied it develops strain ( which is the ratio of change in dimension to the original dimension).
