  1. Scalar vs vector
    • Scalar: physical quantity with magnitude, no direction
    • Vector: physical quantity with magnitude and direction
  2. Rules for adding vectors, subtracting vectors
    • Adding: tail of second to heads of first, then connect tail to head.
    • Subtracting: put both heads together and connect tails or add negative of vector being subtracted
  3. What are the rules for scalar, vector interaction
    • 1: Scalars cannot be added or subtracted from vectors
    • 2: Vectors can be multiplied or divided by scalars. only the magnitude,not direction changes
  4. Rules for multiplying/dividing vectors
    1: first check to see if product is scalar or vector; if a vector the direction is perpendicular to original two vectors times sine of the angle between them (Vp= V1V2sine(theta)) use right hand rule to determine which direction; if a scalar, product equals product of two vectors times cos of the angle between them
  5. Def component vector
    Component vector: two vectors placed perpendicularly to one another,whose sums equal the resultant vector.
  6. Special triangles
    • 1: 3-4-5
    • 2: 5-12-13
  7. Linear motion equations and requirments
    • Xf=Xi+at+(1/2at^2)
    • V=Vi+at
    • V^2=Vi^2+2ax
    • Vavg= (Vf+Vi)/2
    • Peak height of a projectile Vi(sin(theta))=sqrt(2gh)
  8. What information is inside of a d/t graph and a v/t graph
    • D/t: displacement vs time. Slope is velocity, area under is not useful
    • V/t: velocity vs time. Slope is acceleration and area under is displacement
  9. Hat factors effect air reaistance
    • Shape
    • Surface area
    • Velocity
    • Mass - does not change force of air resistance, but the effect of air resistance on an object. The force of air resistance is constant on an object. So F=ma and F is constant, as m increases, a must decrease, so a heavier object accelerates slower than a smaller one.
