Terminal velocity is the highest velocity attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force and the buoyancy is equal to the downward force of gravity acting on the...

Most accidents occur when there is an unplanned transfer of energy from one place to another. As an example, a hammer dropped from a height will have kinetic energy, and when the falling hammer is stopped by hitting another object it will exert a force...
