The acid test start learning		a crucial trial to prove whether or not something works
back-to-back testing start learning		trials to compare two different solutions, in the same conditions
in the field start learning		outdoors, in a real situation
mock-up start learning		a 3D model simulating shape and size, but without internal components
trial run start learning		a practical test of something new or unknown to discover its effectiveness
tried-and-tested start learning		proven to be reliable through real use I trials
validate start learning		prove theoretical concepts by testing them in reality
virtual start learning		describes something simulated by software, not physical

bending start learning		shape or force (something straight) into a curve or angle
centrifugal force start learning		a force, arising from the body's inertia, which appears to act on a body moving in a circular path and is directed away from the centre around which the body is moving
contraction start learning		the process of becoming smaller
expansion start learning		the action of becoming larger or more extensive
friction start learning		the resistance that one surface or object encounters when moving over another
