Uniform linear acceleration Introduction This topic is about particles which move in a straight line and accelerate uniformly. Problems can vary enormously‚ so you have to have your wits about you. Problems can be broken down into three main categories: Constant uniform acceleration Time-speed graphs Problems involving two particles Constant uniform acceleration Remember what the following variables represent: t = the time ; a = the acceleration ; u = the initial speed ; v = the final

involved in economics. Some argue‚ the process is not focused on linear (Sayes 2012; Hughes 2000). An analyses of Ziziphus mauritiana linkage and production process‚ shows that they are a complex web of economic inter-linkages). Contrary to being linear as often suggested. Instead‚ value chains are more space‚ time and socially constructed. The study noted with concern that value chain has been and is still being described as linear (Ash 2013).

rotate about an axis opposes any change desired to be produced in its state of rest or of rotation‚ showing that it possesses inertia for this type of motion. It is the rotational inertia of the body‚ which is called moment of inertia. In case of linear motion‚ the inertia of a body depends on wholly on its mass. In case of rotational motion‚ the inertia depends not only on its mass of the body but also on the effective distance of its particles from the axis of rotation. So‚ two bodies of the same

Elements The inertia elements include masses for translation and moments of inertia for rotation. The mass is usually denoted by m with unit as kg or slug. The moment of inertia often represented as J with unit as kg − m. 3.2.2 Spring Elements A linear spring is a mechanical element that can be deformed by an external force such that the deformation is directly proportional to the force or torque applied to it. For a translational spring‚ the relation between the acting force F and the net displacement

Translational motion Translational motion is the aspect in which a body moves from a specific point to the next. This can be in terms of objects‚ molecules or atoms. This kind of motion normally takes place in a straight line for instance bullet which is fired by a gun. The object in motion does not change by turning on its axis for it travels in a straight line. Any slight change or rotation can cause the object to change direction in general making it not move toward the specified direction.
