Included in this zip folder are 18 Power Point files. 13 are assignments, 3 are introduction files and 2 are student reference printables.
Intro #1 is a 50 slide presentation. The emphasis is understanding acceleration, constant acceleration and gravity. 16 formative assessment problems are embedded in the presentation that use the formula a=(vf-vi)/t.
Intro #2 is 15 slide file. The formula df=.5at^2+vit+di is derived from 3 simple motion formulas.
Intro #3 is a 76 slide instructional file. The parts of the parametric equations needed to solve and graph 2 dimensional projectiles are intricately discussed. The topics include:
1. x component of the initial velocity vector
2. y component of the initial velocity vector
3. Modeling the projectile with a graph
4. Finding the 3 coordinates of the vertex of the parabola (x,y) and parameter, t. This is done by the -b/(2a) method.
5. Finding the 3 coordinates of where the projectile hits the ground (x,y) and parameter, t. This is done by the quadratic formula.
6. Finding the coordinates of these points accurate to 2 decimal places using a TI 30XS multi-view calculator.
Student printable #1 is 1 page. It includes:
1. The difference between speed and velocity
2. The difference between distance and displacement
3. 2 degree separation between displacement and acceleration
4. Derived, df=.5at^2+vit+di
Student printable #2 is 1 page. It includes:
1. The definition of acceleration
2. When acceleration is negative
3. Mapping signs of velocity and acceleration
4. gravitational constants with a few example problems
Assignments A-F are reviews of the 2 average velocity formulas and the acceleration formula. These assignments can be printed or used at socrative.com. The socrative share numbers are included in the files. A brief description of each:
Assignment A is a 15 question multiple choice assignment over vector and scaler quantities.
Assignment B is a 15 question multiple choice assignment. The emphasis is knowing when average velocity can be found using v=.5(vi+vf). Also, displacement vs distance is emphasized.
Assignment C is a 15 question short answer assignment. The emphasis is using the 3 basic formulas and answering with the correct units.
Assignment D is a 15 question multiple choice assignment. The emphasis is using the acceleration formula.
Assignment E is a 15 question multiple choice assignment. The emphasis is the mapping directions of velocity and acceleration.
Assignment F is a 15 question multiple choice assignment. The emphasis is mapping directions of velocity and acceleration as well as some gravity problems.
Assignment #1 is a 24 question multiple choice assignment. The emphasis is finding points on the plane given parametric equations. It is on 1 page for easy printing.
Assignment #2 is a 24 question multiple choice assignment. The emphasis is understanding, recognizing and making parametric equations for 2 dimensional motion. It is on 1 page for easy printing.
Assignment #3 is a scripted problem. The student:
1. Writes the initial velocity vector in both polar and rectangular form
2. Writes the parametric equations needed
3. Fills out a table of values over a given time interval
4. Models the motion with a graph
5. Finds, accurate to 2 decimal places, the coordinates of the vertex and where the projectile hits the ground.
