When doing an experiment, what is the difference between theoretical and experimental values?

Answer 1

OK, you're going to reproduce Galileo's experiment on the Tower of Pisa. Theory says that objects of different mass should fall at the same rate. Use the s = (1/2)*g*t^2 equation to predict how long it will take for your objects to hit the ground. That's the theoretical value.

Then take several measurements of the time for actual objects to hit the ground with the best setup you can come up with. The experimental values will vary from the theoretical, perhaps a few times less, a few times more, hopefully only by a fraction of a second each time. If you have a good setup, and take a lot of data and calculate an average you should get pretty good agreement.

Answer 2

Well this depends on the experiement!

The experimental values are never going to exactly match the theoretical values due to errors in the experiment.

The difference between the 2 values can be used as an indication of how well the experiment was carried out.

eg. an experiment which obtains a value of g (acceleration due to gravity) to be 9.9m/s could be said to be better than one which obtained a value of 10.3m/s.

Answer 3

A theoretical value is one that is obtained through mathematical means and is generally accepted by the scientific community to be the true value, an experimental value is obtained through experiments and may vary slightly from one experiment to another.

Answer 4

Experimental values are the values you get based off your test or the set of documents given jointly as the Theoretical values are the actual international actual values of that difficulty. Theoretical values are often given to you by potential of the priority jointly as you will be able to desire to locate the Experimental.

Answer 5

Greetings!

A theoretical statement is what one would imagine. For example Einstein, Hawkings are theoretical physicists.
Now, when they or others take the statement and begin to create values which enforce the statement, it becomes experimental. When and if and seldom, when you can conduct the experiment numerous times achieving the same result, it becomes law.

Good Luck
