Conceptual Physics Alive: Linear Motion

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 Ques
