In notes today: We copied the equations we found using our graphs of motion last week into regular notebooks for easy access and use:
average velocity = change in position / time
change in position = 1/2 * acceleration * time^2
acceleration = change in velocity / time
Ranking Task: acceleration today - a challenge to agree on.
Homework: Prepare your lab journal for tomorrow's acceleration lab: Title lab, TOC, p#, pre-lab:
1. Sketch a motion map of a car rolling down a ramp (predict its motion)
2. If an object accelerates at 1.4 cm/s^2, find:
a. its position at 4.0s
b. its velocity at 4.0s
Honors Physical – Earth Science Unit2 Motion Objectives
1. Represent and analyze the motion of an object graphically.
2. Analyze the velocities of two objects in terms of position and time
(verbally, with diagrams, graphs, and mathematically)
3. Measure and analyze an object’s motion in terms of speed, velocity, and acceleration
(verbally, with diagrams, graphs, and mathematically)
4. From graphed data, determine how an object is moving, and predict its motion for times/situations outside graph.
5. Describe how a graph of a rate of change of one variable relates to others (using slope and units)
