NOT objects density, not color, and not relative speed between air and object

To determine the terminal speed of an object, several factors come into play. Let's go through the options and see which ones are relevant:

1) Color: The color of an object does not directly affect its terminal speed. It is unrelated to the physics principles governing terminal velocity.

2) Weight: The weight of an object does play a role in determining its terminal speed. Heavier objects will experience a higher gravitational force, which can influence the rate at which the object accelerates towards its terminal velocity.

3) Air density: Air density is a significant factor in determining an object's terminal speed. Higher air density increases the resistance or drag force acting on the object, affecting how quickly it reaches terminal velocity.

4) Object's density: The density of the object itself does not directly impact its terminal speed. However, it can influence the object's weight, which affects the terminal speed (as mentioned in point 2).

5) Shape/Aerodynamics: The shape and aerodynamics of an object are crucial determinants of its terminal speed. Streamlined and aerodynamically shaped objects encounter less air resistance, allowing them to reach higher terminal velocities.

6) Relative speed between air and object: The relative speed between the air and the object does not directly affect the object's terminal speed. The object's terminal speed is determined by the forces acting on it, primarily gravity and air resistance.

7) Surface area encountered by air: The surface area of an object encountered by air is directly related to the object's terminal speed. Objects with larger surface areas experience increased air resistance, which can slow down their acceleration towards terminal velocity.

In conclusion, the factors that determine the terminal speed of an object are weight, air density, shape/aerodynamics, and surface area encountered by air. So for this question, the applicable options are 2, 3, 5, and 7.
