Unformatted text preview: ain to estimate its velocity in km/h at t = 40 min. Example: PHYS 1L03, Fall 2013, McMaster University, R. Nejat One-Dimensional Motion Example: • The position of a particle as a function of time is given by the curve shown below. Find the instantaneous velocity at time t = 2 s. When is the velocity greatest? When is it zero? Is it ever negative? What is the average velocity of this particle between t = 2 s and t = 5s? PHYS 1L03, Fall 2013, McMaster University, R. Nejat One-Dimensional Motion Example: velocity at t=2 s? Greatest velocity ? PHYS 1L03, Fall 2013, McMaster University, R. Nejat PHYS 1L03, Fall 2013, McMaster University, R. Nejat 8 One-Dimensional Motion One-Dimensional Motion Example: Zero velocity? Negative velocity? Average velocity? • Having the same top speed, how an African lion can catch a Cape buffalo? PHYS 1L03, Fall 2013, McMaster University, R. Nejat One-Dimensional Motion Acceleration: • is a vector. • indicates how fast and in what direction an object’s velocity is changing. • is a rate of chan...
