    Study Notes

    Quadratic Functions in Real-life Applications

    Quadratic functions are mathematical equations that have the form ax² + bx + c. These functions are widely used in real-life scenarios. They are particularly useful in physics, where they describe the motion of objects in parabolic paths, such as the trajectory of a thrown ball.

    Ball Throwing

    In a classic example, a ball thrown into the air follows a quadratic path. The height of the ball is a quadratic function of the time it's in the air. This is because the acceleration due to gravity is constant, and the parabolic motion of the ball follows the quadratic equation: h = -16t² + vt, where h is the height, t is the time, and v is the initial velocity.

    Parabolic Motion

    Parabolic motion is the path followed by a projectile that's thrown into the air and is subject to constant acceleration. This type of motion is described by the quadratic equation y = -16t² + vt, where y is the height, t is the time, and v is the initial velocity. The maximum height is reached when the time t is equal to v/16.

    Ball Dropping

    When a ball is dropped from a certain height, the distance it falls follows a quadratic equation. The distance x is a quadratic function of the time t: x = 16t².

    Everyday Scenarios

    Quadratic functions are used in various everyday scenarios. For example, they can be used to calculate the area of a room or a plot of land, where the area is a quadratic function of the length and width. Quadratic functions are also used in business to determine the profit, where the profit is a quadratic function of the price. In athletics, quadratic equations are used to calculate the time it takes for a ball to reach a certain point or to estimate the speed of an object.

    In summary, quadratic functions play a significant role in our daily lives, from calculating areas to determining the time it takes for a ball to reach a certain point. They are fundamental in understanding the motion of objects in parabolic paths and are used in various fields, including physics, business, and athletics.
