2.04A - I can interpret/draw velocity vs. time graphs for objects moving with constant velocity.
2.04B - I can use a velocity-time graph to determine acceleration and starting velocity. I can distinguish the concepts of velocity and acceleration.
2.05B - I can calculate the distance an object has traveled and its change in position from a velocity-time graph

Can you...
- Describe the motion of an object including its direction of motion, relative speed, whether it shows constant velocity or accelerated motion, and whether it is speeding up or slowing down.
- Draw a velocity-time graph from a given written description.
- Determine the displacement of the object (area under curve).
- Draw a motion map for the object.
- Write a mathematical model to describe the motion.
Initial position: y intercept
Distance or displacement: change in y values
Direction of motion: Sign of the slope - Positive slope (positive direction) or Negative slope (negative direction)
Relative speed: Steepness of the slope
Calculating velocity, speed, and initial velocity: Calculate the slope
Constant speed/speeding up/slowing down: is the slope constant, getting steeper, or getting shallower
Acceleration: is the slope getting more positive or more negative
Distance or displacement: change in y values
