Paper airplane contest
We investigate the 3rd law of motion via a paper airplane contest.
In the time that remains, we investigate the 2nd law of motion.
F=ma
Define variables, units
Investigate relationships

Test on projectile motion
Test on projectile motion.
Following the test, a puzzle on Newton's Laws of Motion, which the sub will assign as class work or home work at the sub's discretion.

Test review, papers returned
Some sample questions from the Conceptual Physics text will be provided, plus information about how the remaining questions will be selected. One or more problem sets will be graded in class. Test is Wednesday, closed book open notes, calculators allowed.
Here is a list of topics for the exam review:
Experimental Design
Hypothesis, Theory, Law, facts
independent, dependent and interfering variables
Constant Speed
Distinguish between speed and velocity
Find distance, speed, and time given two of the three quantities for constant speed.
Distinguish between instantaneous and average speed.
Constant Acceleration in a Line
Determine speed, acceleration, and position using x(t) equation
Determine acceleration if change in position and time is given.
Determine distance fallen and final speed of dropped objects
Sketch d vs. t and a vs. t graphs for objects and explain what is happening in words, and vice versa.
Vectors
Be able to add vectors graphically.
Break vectors into x and y components.
Projectile Motion
Solve three types of problems: Objects thrown straight up, objects shot horizontally off of cliffs, and objects thrown at an angle. Given initial velocity, position, and angle, find time of flight, maximum height, and range as appropriate.
Explain the behavior of objects' x and y velocity components while in flight.
Understand that while y velocity can be zero, acceleration cannot be for objects flying through the air.

Homework NOT due; Grade status
Previously assigned homework is NOT due today as stated in previous post; we haven't gone over everything yet.
Today we work many sample projectile motion problems.
Grades will be computed as much as possible.
