Hii,
We hear the term accuracy and precision almost every time during performing experiments of physics.But most of the time we think both are similar.Answer is no.An experiment is accurate if it matches with exact desired value but precision is getting similar values time and again but not the exact value.Let me give you one example,suppose you are performing an experiment to get the value of g(acceleration due to gravity) whose exact value is 9.8.Now while performing this experiment if value comes to be 9.8 it is accurate but if you record 3 values like 8.7,8.6,8.8 they are considered to be precise not accurate.Thus precision is about getting close values each time and accuracy is getting the exact value.I hope it is clear now.
Thanks...
