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

Even though college algebra is considered to be an obstacle for many students in terms of degree completion‚ as teachers we must teach useful strategies to motivate our students to find interest in mathematics. Recently‚ there is a psychological problem that we as teachers will face in the future‚ which is that some students believe they were born incompetent in math. However‚ “effort is key to their success and failure is a result of a lack of effort” (Cortes-Suarez‚ 2004). As teachers‚ we must
