1. GENERAL PHYSICS 1

2. At the end of the lesson, the students shall be able to 1.define accuracy and precision 2.differentiate accuracy from precision 3.apply accuracy and precision in real life situation.

3. Terminologies: 1.Accuracy- It refers to the closeness of the given set of values to the correct values. (bulls-eye) The closer the darts are to the bulls-eye, the more accurate they are.

4. 2.Error- It refers to the difference between the calculated value and actual value.

5. 3.Precision- It refers to the closeness of the values to each other. The nearer the darts are to each other, the more precise they are. 4. Uncertainty- It refers to a usually described as an error in measurement

6. Accurate or Precise? Tell whether the situations are: A. accurate B. precise C.accurate but not precise D.Not accurate but precise

7. 1.If a thermometer reads 75 degree Farenheit outside and it really is 75 degree farenheit.

11. 2. If the thermometer consistently registers the exact temperature for several days in a row.

12. 3. A refrigerator thermometer is read ten times and registers degrees Celsius as: 39.1, 39.4, 39.1,39.2,39.1,39.1,39.4, and 39.1. However, the real temperature inside the refrigerator is 37 degree Celsius.

13. Answer: 1.Accurate 2. Precise 3.Not accurate but precise
