Absolute pressure is a pressure that is relative to the zero pressure in empty air-free space. 2nd Equation of Motion Final Position Calculator This equation applies to a particle moving linearly, in three dimensions in a straight line, with constant acceleration. Since the vectors are collinear ...
E. Circular motion is always accelerated, as is simple harmonic motion (indeed, uniform circular motion is one example of simple harmonic motion.) However, simply because an object is moving in a straight line does not guarantee non-acceleration; imagine dropping an object, for example. 2. B...
