Performing the Chemical Test by Reagent Strip The urine must be collected using appropriate technique and be tested within one hour ofcollection. If tests cannot be performed within this time, the specimen may be refrigerated for upto 8 hours.
Elastic and Inelastic Collisions. A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision. An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. Any macroscopic collision between objects will convert some of the kinetic energy into internal energy and other forms of energy, so no large scale impacts are perfectly elastic.
If the bodies collide and stick together, the. collision is called perfectly inelastic. In this case, much of the kinetic. 3Notice there is no arrow over the velocity variable in the equation for kinetic energy. Last updated October 5, 2014 55. 5. Inelastic Collisions. energy is lost in the collision. That is, much of the kinetic energy is converted. to other forms of energy. In the following two experiments you will be dealing with a perfectly. inelastic collision in which much of the kinetic energy is lost, and with a. nearly elastic collision in which kinetic energy is conserved.
