which is more accurate, calculating terminal velocity from a position vs time graph or a velocity vs time graph
Calculating terminal velocity from a velocity vs time graph is more accurate compared to calculating it from a position vs time graph.
Terminal velocity is the constant maximum velocity achieved by an object during free fall or motion through a fluid when the force of gravity is balanced by the drag force. It occurs when the object's acceleration becomes zero and the net force acting on it becomes zero.
In a velocity vs time graph, the terminal velocity can be identified as the point where the velocity curve levels off and becomes horizontal, indicating that the object has reached its maximum velocity and is no longer accelerating. This makes it easier and more accurate to determine the terminal velocity.
On the other hand, in a position vs time graph, determining the terminal velocity can be more challenging. The position vs time graph shows the displacement of the object over time, which can also be affected by other factors such as the initial position or any external forces acting on the object. These additional factors can introduce errors and make it more difficult to precisely determine the terminal velocity.
Therefore, calculating terminal velocity from a velocity vs time graph is generally more accurate and reliable.
