INTRODUCTION & RECTILINEAR KINEMATICS: CONTINUOUS MOTION Today s Objectives: Students will be able to: 1. Find the kinematic quantities (position, displacement, velocity, and acceleration) of a particle traveling along a straight path. In-Class Activities: Applications Relations between s(t), v(t), and a(t) for general rectilinear motion. Relations between s(t), v(t), and a(t) when acceleration is constant Group Problems Solving

APPLICATIONS The motion of large objects, such as rockets, airplanes, or cars, can often be analyzed as if they were particles. Why? If we measure the altitude of this rocket as a function of time, how can we determine its velocity and acceleration? As long as the motion is characterized by the motion of its mass center and any rotation of the body is neglected .

RECTILINEAR KINEMATICS: CONTINUOUS MOTION (Section 12.2) A particle travels along a straight-line path defined by the coordinate axis s . The total distance traveled by the particle, s T , is a positive scalar that represents the total length of the path over which the particle travels.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
