Does constant velocity mean no acceleration? If an object is changing its velocity -whether by a constant amount or a varying amount – then it is an accelerating object. And an object with a constant velocity is not accelerating. Is there work with constant velocity? When an object is moving with constant velocity, it means […]

How can we identify sedimentary rocks?
How can we identify sedimentary rocks? If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders. Their names are based on their clast or grain size. The smallest grains are called clay, then silt, then sand. […]
