From Chapter 2 (MotionAlong A Straight Line) select and explain in your own words two ofthe following 6 learning goals. Then find someone else postdiscussing a different learning goal than you explained, reviewtheir explanation and add anything they may have missed that youfeel is important.
2.1 - How do the ideasof displacement and average velocity help us describe straight linemotion?
2.2 - What is themeaning of instantaneous velocity; and what is the differencebetween velocity and speed?
2.3 - How does one useaverage acceleration and instantaneous acceleration to describechanges in velocity
2.4 - How does one useequations and graphs to solve problems that involve straight-linemotion with constant Acceleration?
2.5 - How does we goabout solving problems in which an object is falling freely underthe influence of gravity alone?
2.6 - How does oneanalyze straight-line motion when the acceleration is notconstant?
