HW: RA 2.2
Check Quia for practice problems on d, v, t, a

Stamped RA 2.1 for completion. Went over RA 2.1 in class.
Showed ball bearing in soap

Intro lecture on motion
avg speed = total distance traveled/total time
instantaneous speed = speed at a specific moment in time (read from speedometer or from graph of v vs t)
velocity = how fast and in what direction
distance = how far (how much gasoline you need)
displacement = how far and in what direction from starting point

acceleration
a = (vf-vi)/t or vf = vi + a * t
Did several examples including hourly wage and yearly pay raise example.

Students did Picket Fence Lab to get introduced to the computers and Vernier equipment.

If weather is good on Wednesday, we will do Rocket Lab

Handed out RA 2.2 due on Wednesday.
