Motion

1. Free Fall: gravity is the only force acting

1.1. acceleration=9.8 m/s2

2. Free Body Diagrams (all forces acting on an object)

3. Equilibrium: Equal and Opposite forces

4. W=mg (F=ma)

5. Air resistance/Drag

6. x- & y- components

7. Solving Problems

7.1. Knowns

7.2. Wants

7.3. Problem Solving Steps

8. More Complex Vectors

9. constant acceleration

9.1. Kinematics Equations

10. 2D Motions

10.1. Free Throw Shot

10.2. Catapult

10.3. Spiking a Volleyball

11. Angle of Elevation

11.1. Trajectory

12. Equations

12.1. change in v=final v-initial v=acc.*change in t

12.2. change in position=1/2(final v + initial v)*change in time

12.3. change in position=initial v*change in time+1/2acc.(change in time)^2

12.4. final v^2-initial v^2=2acc*change in position
