Chapter 3: Describing Motion Velocity
One-Dimensional Kinematics
Kinematics motion with out regard for how it is caused.
One-dimensional straight line
Position, Distance, and Displacement
Position separation from reference point
Distance total length of travel
Displacement change in position, d
d = d2 d1
Average Speed and Velocity
Average Speed = distance/elapsed time
Average Velocity = displacement/elapsed time
vav = d/t = (d2 d1)/(t2 t1)
Velocity = Slope of position-time graph
