Err...djester555 said:how do i calculate cross-sectional area?
Drag force is a resistive force that acts opposite to the direction of motion of an object moving through a fluid, such as air or water.
The strength of drag force is affected by the speed of the object, the density of the fluid, the cross-sectional area of the object, and the shape of the object.
Terminal speed is the maximum speed that an object can reach when falling through a fluid, when the drag force balances out the force of gravity. At this point, the object will no longer accelerate and will fall at a constant speed.
Terminal speed is directly related to drag force. As the drag force increases, the terminal speed decreases. This is because a greater drag force will slow down the object faster, thus reaching its maximum speed at a lower rate.
No, terminal speed cannot be exceeded for an object falling freely through a fluid. However, if the object has an external force acting on it, such as an engine propelling it forward, it can reach higher speeds.
