Questions: How are vectors used to analysis 2 dimensional motion? Does a bullet hit the ground at the same time as a bullet dropped from the same height? What: Analyze motion that is independently moving in two or more dimensions at the same time. Examples include airplanes and boats that are moving in water or air and independently carried by the wind or water in a different direction. Projectiles that are moving horizontally at a constant speed, but accelerating vertically. Why: To accurately predict the position speed, time, velocity of an object in any plane we can analyze each component of motion as a form of linear motion and then recombine as necessary to evaluate the problem. How: Video Myth Busters bullet fired/dropped Drew Breeze football Marble drop in class Calculate the position of an object moving horizontally at 2 m/s for each second for 5 seconds Calculate the position and speed of an object starting from rest and free falling for each second for 5 seconds. Create a scaled plot for each on one diagram on the board. Create the parabola (trajectory) Develop a procedure for analyzing the motion, to find any unknown knowing a few details.

Assignment: Practice Set D p 99 all By end of class Ss should be able to analyze a horizontal projectile and understand the independent nature of projectile motion.

Review HW Set D Materials: Marbles, labquests (Charge!), ramps, meter sticks. Use your knowledge of horizontal projectiles to launch a marble off of a table top and calculate where the marble will land. Place a Dixie cup where your mathematical calculations suggest and on the first try land the marble in the cup. Use LAbquest to determine the speed of the marble.

How can this be extended to projectiles fired at an angle? Marshmallow cannon? Read Holt P 99-100 and complete practice set E #1-4.

By End: Be able to fully analyze horizontal projectiles and visually confirm the validity of the mathematics.

What: Analyze projectiles launched at an angle and at an angle with the horizontal. Why: Analyzing motion in 2 dimensions is very complex, but if each motion is decomposed into two or 3 independent motions then each component can be analyzed using the linear motion equations previously studied and the added back together if necessary. How: Practice worksheets horizontall and launched at an angle

Above Nov. 26 Continued. Quiz on horizontal and vertical projectiles. 1 each quick 10 minutes total.

Finish projectiles launched at an angle and discuss relative velocity.

What is relative velocity. Describe the position or speed of an object relative to another object or point. Remember from the beginning of school we described motion as being relative to.... Now be able to describe motion of an object that is moving to another moving reference frame. Why: often times the objects we see are moving at the same time we are, but perhaps in a different direction. How does one observer see the same event the same or differently than another? How: imagery, class examples, the moving river. practice problems
