Study Notes
Projectile Motion
- Projectile motion is the motion of an object influenced by gravity.
- The height of the object can be described by the following equation:
- $h(t) = \frac{1}{2}at^{2} + V_{0}t + y_{0}$
- Where:
- $h(t)$ represents height
- $t$ represents time
- $a$ represents acceleration
- $V_{0}$ represents initial velocity
- $y_{0}$ represents initial height
- Where:
- $h(t) = \frac{1}{2}at^{2} + V_{0}t + y_{0}$
- Zeros of a projectile equation represent the points where the object hits the ground (x-intercepts/roots).
Growing Steps Pattern
- The number of squares in each step follows a pattern:
- Step 1: 1 square
- Step 2: 4 squares
- Step 3: 9 squares
- The equation $y = n^2$ describes the number of squares in the pattern, where 'n' represents the step number.
Quadratic Quiz
- Linear Functions
- General form: $Ax + By = C$
- Example: $y = 350 + 50m$
- Exponential Functions
- General form: $y = ab^x$ or $y = a (1+r)^x$
- Quadratic Functions
- General form: $y = ax^2 + bx + c$, $y = a(x - m)(x - n)$, or $y = a(x - h)^2 + k$
- Example: $y = x^2$
- Parabolas
- U-shaped curves whose direction depends on the value of 'a':
- When 'a' is positive, the parabola opens upward ($∪$).
- When 'a' is negative, the parabola opens downward ($∩$).
- U-shaped curves whose direction depends on the value of 'a':
- Vertex of a Parabola
- The minimum point of the parabola when 'a' is negative.
- The maximum point of the parabola when 'a' is positive.
Measuring a Garden
- Noah has 50 meters of fencing to create a rectangular garden.
- Students are asked to:
- Draw different rectangular garden shapes with varying lengths and widths.
- Calculate the area of each rectangle.
- Identify the length and width combination that results in the largest possible area.
- Plot the length and area values on a coordinate plane to visualize the relationship.
