Once you have solved the appropriate equations for the variable you are asked to solve for, it is time to plug in the given values.
The commonality is in the use of a method to get what you are looking for.
Let's look at a method to solve any physics 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.
For example, if it's a force problem asking for the mass of the object, we would write: mass?
This may seem unnecessary, but it really helps to keep your progression through the problem organized and focused. Once you decide on an approach you have to look for equation(s) that contain the variables in the given and unknown that you already wrote down.The substitution stage involves plugging in the given values and coming to an answer.The solve stage is where the answer is evaluated to determine if the answer is realistic. We have over 200 college courses that prepare you to earn credit by exam that is accepted by over 1,500 colleges and universities.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.Try it risk-free Physics is a subject that can't be memorized, but strategies for solving problems are applicable across all types of physics problems.In this lesson, we will go through a method to approach any physics problem. Your teacher probably first taught you the sounds of each letter in the alphabet.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!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.
