This incident was not unique. Fatalities from welding and hot work are often are associated with confined spaces and the areas adjacent to these confined spaces . The CSB has identified over 60 fatalities since 1990 due to explosions and fires from hot work activities on tanks, which are, of course, confined spaces.
moÂ·menÂ·ta (-tÉ) or moÂ·menÂ·tums. 1. Symbol p Physics A quantity used to measure the motion of a body, equal to the product of the body's mass and its velocity. Also called linear momentum. 2.
I think you mean conservation of momentum. Conservation means to keep or to save. In this phrase, it means that momentum (velocity X mass) is conserved. Meaning that the total momentum of any closed system (one not affected by external forces) cannot be changed. Momentum is a vector quantity-it has direction.ating Newest Oldest. Best Answer: Actually, it is conservation, NOT conversation of momentum, which means that the total momentum of a closed physical system (i.e. no external forces acting on the system) remains the same always, no matter what happens over time.
