From Chapter 2 (Motion Along A Straight Line) select and explain in your own words two of the following 6 learning goals. Then find someone else post discussing a different learning goal than you explained, review their explanation and add anything they may have missed that you feel is important.
2.1 - How do the ideas of displacement and average velocity help us describe straight line motion?
2.2 - What is the meaning of instantaneous velocity; and what is the difference between velocity and speed?
2.3 - How does one use average acceleration and instantaneous acceleration to describe changes in velocity
2.4 - How does one use equations and graphs to solve problems that involve straight-line motion with constant Acceleration?
2.5 - How does we go about solving problems in which an object is falling freely under the influence of gravity alone?
2.6 - How does one analyze straight-line motion when the acceleration is not constant?
