PHYS 2211 - Principles of Physics I
Lesson 3 - One-Dimensional Motion II

Study Assignment:

Chapter 2, Sections 2.5 - 2.7

Lesson notes:

This lesson applies the deinitions of the kinematic qauntities introduced in Lesson 2 to the special (but important) case of constant acceleration.

Objectives:

1. Be able to use the one-dimensional, constant acceleration equations to solve problems.

2. Be able to use the fact that freely falling objects undergo constant acceleration to solve free-fall problems as one-dimensional kinematics problems.

3. Be able to derive the kinematic equations for constant acceleration from basic definitions using differential and integral calculus.

Vocabulary:

free-fall
acceleration due to gravity

Homework:

TQ: 2-11
TP: 2-23, 2-27, 2-38

Additional Information:

A short biography of Galileo Galilei is provided by the University of St Andrews in Scotland.

Rice University maintains the Galileo Project, a Web site devoted to the life of Galileo Galilei.

A demonstration of freely falling objects in vacuum as performed by the Apollo 15 astronauts on the Moon is provided by this video.
