Kinematics PART 1

Displacement, velocity, acceleration and time Engineers often wish to predict what will happen under certain circumstances and mathematics is a useful tool for making such predictions. I have known highly competent workshop engineers who were very wary of mathematics but, as I have found with machine tools, practice makes, if not perfect, at least less nervous! This article will examine the equations of motion under constant acceleration, looking later at one of the most powerful tools in the mathematical workshop. The equations of motion under uniform acceleration Most people are probably happy enough with the following expression: However, to treat this subject formally, we note that speed is a scalar quantity (i.e. direction is not specified) whereas velocity is a vector quantity (i.e. its definition includes direction). We should also…
