Physics problems are generally those dreaded word problems.
You can't read a physics problem like you would read a newspaper article or a novel.
Staying organized and on track is very important to solve any problem correctly and efficiently.
The acronym GUESS stands for: and is an effective method for approaching any physics question.
Drawing a sketch can also help you identify information involved in the scenario that isn't explicitly expressed in the problem, such as the acceleration due to gravity.
In a space separate from the given or in the sketch itself, write down what you are looking for with a question mark after it.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.This way, if you make a mistake, it is easier to find it.Sifting through numbers is much more difficult for finding mistakes.For example, if you are working on a kinematics problem and the velocity is given in km/hr and your acceleration is in m/s, you need to convert the time and distance units so they match.There is one step left, which is to solve the problem!GUESS is an acronym for the strategy we will use to solve any physics problem.The letters stand for: Let's go through each of these steps in more detail.Unfortunately, mistakes do happen when solving physics problems, and it requires you to go back to the beginning to find the mistake. Let's work a sample problem where we implement the GUESS method to solve it.Here's our prompt: A person drops a rock from rest from a 115 m high bridge.
