[[Falsifiability]] is a frequently used criterion in determining whether a particular hypothesis is [[science|scientific]] or conjecture. A hypothesis is considered falsifiable if it ''could'' be proven wrong by experiment. This concept falls under the category of [[Philosophy of Science]] and is a useful tool in determining the scientific validity of a hypothesis, although not a complete test in and of itself.

For instance, the proposition "Gravity accelerates objects towards the Earth at 32 ft/s<sup>2</sup>" can be tested by dropping an object in Earth's gravitational field. If we did this and it didn't fall, or it fell at a different speed, we would know that the proposition is false.
