The Strange Situation This is a method devised by Ainsworth and Bell to measure the type of attachment that a child has formed. It uses many terms and concepts that you should already be familiar with from earlier work in the topic, e.g. Glasgow Babies and the Love Quiz.
In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. This pressure difference results in a net upwards force on the object.
