Answer:
I OFTEN LOOK in case stuff falls.
Step-by-step explanation:
We usually call this movement "free fall" because the body only falls under the influence of gravity. The body is continuously accelerating with its gravitational force alone and the motion is simple to model.
Yet objects on the Earth's surface typically also have a power for air resistance.
Air Resistance Modeling——————————Let's tell you I drop a ball of tennis. I can draw a force diagram as it falls.
The most common air resistance model states that the force magnitude depends on: air density (μ). The value normally is approximately 1.2 kg / m3.
The object's cross-sectional area (A). The cross-section area of a table tong would be equal to μ*r2.
The drag factor (C). The shape of the object depends on this. A unitless value of 0.47 is common for a spherical object.
The speed squared in magnitude. The quicker you go, the more air resistance.
