Question

describe a experiment to demonstrate terminal velocity.say what are the measurement s you need to take in your experiment to show that a falling object has reached terminal speed​

Answer 1

An object will have terminal velocity if the weight of it becomes to the restraining force exerted by the fluid. In this condition body has constant speed and freely falling.

Explanation:

In the experiment you need to measure the mass of the object only. Then, Multiply mass with 2. After that multiply that number with 9.8 ms^(-2). The density of the fluid through which object falls is always known. Next, multiply that density with the obtained number in the previous step.
