Nejat 5 One-Dimensional Motion One-Dimensional Motion Average Velocity: defined as Velocity: vaverage • is a vector. xf xi tf ti x t • indicates how fast and in what direction an object is moving. • is the rate of change of an object’s displacement. • Depends on both the displacement and the time interval PHYS 1L03, Fall 2013, McMaster University, R. Nejat One-Dimensional Motion Average Velocity: vaverage x2 t2 x1 t1 One-Dimensional Motion vaverage • Average velocity is the slop of the straight line connecting two points on the position vs time graph. PHYS 1L03, Fall 2013, McMaster University, R. Nejat xf xi tf ti x t x t (omitting vector signs). • Unit of v is m/s Position-versus-time graph PHYS 1L03, Fall 2013, McMaster University, R. Nejat B Example: • A train passes through Hamilton. At 3:14 p.m., the train is 3 km east of the city centre. At 3:56 p.m., the train is 26 km west of the city centre.
