Uniform Motion
Uniform Motion Objectives:
UM.1 recognize the difference between vector and scalar quantities, treating velocity as a vector distinguishing between magnitude
and direction
UM.2 describe relationships between distance, time, and speed
UM.3 write the linear formula for a position vs time graph of constant velocity motion, identifying the meaning of the slope and
y-intercept
UM.4 identify the slope of the tangent to a point on a position vs time graph as the instantaneous velocity of the object
UM.5 know the difference between position, distance, and displacement
UM.6 interpret/draw motion maps for objects moving with constant, increasing, and decreasing velocity
UM.7 interpret/draw the position vs. time graph for objects moving with constant, increasing, and decreasing velocity
UM.8 interpret/draw the velocity vs. time graph for an object moving with changing velocity
UM.9 draw the corresponding position vs time graph or motion map given a velocity vs time graph
UM.10 distinguish between and be able to calculate average speed, average velocity and instantaneous velocity
