Which of the following determine the terminal speed of an object? Choose all that apply.
Weight
Color
Object's density
Air density
Relative speed between the object and the air
Shape/Aerodynamics
Surface area encountered by air
The terminal speed of an object is determined by the following factors:
1. Weight: The weight of the object affects the force of gravity acting on it.
2. Object's density: The density of the object affects its ability to displace air, which in turn affects the air resistance experienced.
3. Air density: The density of the air through which the object is moving affects the resistance it encounters.
4. Relative speed between the object and the air: The speed at which the object moves through the air influences the air resistance it experiences.
5. Shape/Aerodynamics: The shape of the object affects how smoothly it moves through the air. A more streamlined shape will experience less air resistance and reach terminal speed more quickly.
6. Surface area encountered by air: The larger the surface area of the object that comes into contact with the air, the greater the air resistance and therefore the slower the object will reach terminal speed.
Therefore, the factors that determine the terminal speed of an object are weight, object's density, air density, relative speed between the object and the air, shape/aerodynamics, and surface area encountered by air.
To determine the terminal speed of an object, several factors come into play. These factors include:
1. Weight: The weight of an object affects its terminal speed. Heavier objects will generally have a higher terminal speed than lighter ones.
2. Object's density: The density of an object impacts how it interacts with the surrounding air. Objects with higher densities tend to have higher terminal speeds.
3. Air density: The density of the air through which the object is moving affects its terminal speed. Dense air will lead to a lower terminal speed.
4. Relative speed between the object and the air: The relative speed between the object and the air it moves through plays a crucial role in determining the terminal speed. As the speed increases, the drag force on the object also increases, eventually balancing the gravitational force and establishing the terminal speed.
5. Shape/Aerodynamics: The shape of an object influences its terminal speed. Objects with streamlined or aerodynamic shapes experience less air resistance, resulting in higher terminal speeds. On the other hand, objects with irregular shapes or a high drag coefficient will have a lower terminal speed.
6. Surface area encountered by air: The surface area of an object that comes into contact with the air affects its terminal speed. Larger surface areas result in higher air resistance, causing a lower terminal speed.
Therefore, among the given options, the factors that determine the terminal speed of an object are: weight, object's density, air density, relative speed between the object and the air, shape/aerodynamics, and surface area encountered by air. Color is not a determining factor in the terminal speed of an object.
