Give an example of a scientific question that could be investigated with an experiment. then give an example of scientific question that could not be investigated in this way.

Explanation:

A scientific question is the one which can be answered after conducting thorough detailed experimental procedure. It is said to be testable. A non-scientific question is the one which cannot be answered using experimental procedures. It is said to non-testable.

The example of a scientific question: Which has more nutritional value milk or butter? The answer of this question can be obtained after experimental trials.

Which is better milk or butter? As no parameter is given for comparison, this question cannot be tested experimentally.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
