 2.1 MOTION IS RELATIVE

Relative Motion
What does the phrase "motion is relative" mean? Find out in this online tutorial from the Department of Physics at the University of Illinois at Urbana-Champaign.
Foucault's Pendulum
Most of the time, the relative motion of the earth does not affect our perception of motion. However, in 1848, Leon Foucault discovered that when a large pendulum swings, the earth appears to "move under it." Learn more about Foucault's pendulum from Dr. Kruszelnicki's fact-filled site.

2.2 SPEED

Average vs. Instantaneous Speed What is the difference between average speed and instantaneous speed? This GIF animation from the Multimedia Physics Studios should clear up any confusion

2.3 VELOCITY

Velocity Learn all about velocity in this chapter from the Learn Physics Today online physics tutorial. It includes graphics, animation, and self-check questions.
Speed and Velocity What's the difference between speed and velocity? Find out by exploring this interactive tutorial from The Physics Classroom
Hot Wheels Track Check out the velocity and acceleration vectors of a Hot Wheels car as it moves around the race track in this GIF animation from the Multimedia Physics Studios

2.4 ACCELERATION

Accelerating Cars
Which car is accelerating? If necessary, review the definition of acceleration. animation from the Multimedia Physics Studios.
Accelerationarn all about acceleration in this chapter from theLearn Physics Today online physics tutorial. It includes graphics, animation, and self-check questions.

2.5 FREE FALL: HOW FAST

Free Fall and the Acceleration of Gravity Free fall is defined as "motion under the influence of gravitational force only." Find out more about free fall in this interactive tutorial from The Physics Classroom.

2.6 FREE FALL: HOW FAR

How fast? and How far? How fast something moves is entirely different from how far it moves. Learn more about fast, far, and free fall in this helpful interactive tutorial from The Physics Classroom
