Term
 How do you subtract vectors?
Definition
 Add one vector to the negative of the second vector
Term
 When multiplying two vectors, what are the two possible products and their formulas?
Definition
 Vector and Scalar   Magnitude of Vproduct = V1V2sinΘ (Points perpendicular to original two vectors)   Magnitude of Sproduct = V1V2cosΘ
Term
 Two types of triangles to know for MCAT?
Definition
 3-4-5 and 5-12-13 triangles
Term
 Explain 'Uniformly Accelerated Motion'
Definition
 Motion with constant acceleration (can be zero acceleration)
Term
 What are the 4 uniform acceleration equations?
Definition
 x = x0 + v0t + 1/2at2   v = v0 + at   v2 = v02 + 2ax   vavg = 1/2(v0 + v)
Term
 What does the slope represent on a displacement vs. time graph?   What does a curved line on the graph represent?   What does the area beneath the graph represent?
Definition
 Velocity   Changing velocity = acceleration   The area has no meaning
Term
 What does the slope represent on a velocity vs. time graph?   What does a curved line represent?   What does the area beneath the graph mean?
Definition
 Acceleration   Changing acceleration   If the entire area between the curve and zero velocity is labled positive, the area represents distance. If negative numbers are included, area represents displacement.
Term
 What is the formula to find the peak height of a projectile?
Definition
 v0sinΘ = √(2gh)
Term
 What dictates the time of flight for a projectile?
Definition
 Only the vertical velocity
Term
 What is the formula to calculate the range of a projectile?
Definition
 Range = Horizontal Velocity x Time in Flight
Term
 What three factors effect air resistance and how?
Definition
 Surface Area: increased surface area = increased air resistance   Shape: Streamlined objects experience less air resistance   Velocity/Speed: Higher velocity = more air resistance
