|
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 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 |
