Conceptual Physics Alive: Linear Motion includes a digital video and questions set with answers.

Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, Paul Hewitt teaches Linear Motion: Concepts of speed, velocity, and acceleration are introduced and supported with a variety of examples. The effect of air resistance on falling objects is also discussed.

Linear Motion Includes:

• Speed is defined as the ratio distance/time.
• Numerical examples of speed are given.
• Speed Is distinguished from velocity.
• Average speed is defined.
• Speed equation is rearranged to read d = vt.
• Numerical examples of distance traveled are given.
• Acceleration is introduced and defined.
• Acceleration In given in equation form: a= chg. in v/t.
• Numerical examples of acceleration are discussed.
• Acceleration of a freely falling object is 10 m/ s2.
• When acceleration is due to gravity, we say g = 10 m/s2.
• Equation v = gt.
• Effects of air drag.

Next-Time Question: For an object thrown straight upward, what is the acceleration at the top of its path? (10 m/s2.) When a piece of paper is placed atop a book that is dropped, which has greater acceleration, the book, or the paper? (SEE RESOURCES TAB FOR MORE)
