Problem: Article: You can measure mass using a balance. A balance is different from a scale because it uses a known mass to measure the unknown mass where as a scale actually measures weight.  Finding mass with a triple-beam balance or a double-pan balance is a form of measuring gravitational mass. This is a static measurement, which means it is only accurate when the object being measured is at rest. A balance can measure weight and mass. Because the measurement of the balance weights change by the same factor as the object being measured, a balance is able to accurately provide the mass of an object regardless of the specific gravity of the environment. Inertial mass is a dynamic measuring method, meaning that it can only be accomplished while the object being measured is in motion. The inertia of the object is used to quantify the amount of matter.  An inertial balance is used to measure inertial mass. Secure the inertial balance to a table. Calibrate the inertial balance by putting the container in motion counting the number of vibrations in a specified time period, for example 30 seconds. Place an item of known mass in the container and repeat the experiment. Continue using several items of known mass to finish calibrating the scale. Repeat the experiment with an item of unknown mass. Graph all results to find the mass of the final object.
Summary: Measure gravitational mass. Measure inertial mass.

Problem: Article: This is usually expressed as a percentage of alcohol by volume on the bottle. The alcohol content of alcoholic drinks can vary greatly. Beers generally do not go higher than 6%, unless they are specially made to taste stronger, wine can be anywhere from 8% to 14%, and hard liquors are generally around 45% to 55% and are poured in much smaller amounts. Unfortunately, the alcohol content may not be listed on the labels of your drink, so if you are uncertain, ask your bartender or liquor store merchant to find out the official alcohol content for you. A great way to keep track of your drinking habits is by marking each drink you have in a journal, your phone, or on a calendar. This shows you exactly how much you've been drinking, and can allow you to notice trends in your habits. Write down your number of drinks in your journal as you consume them to keep an accurate total. It's very important that you are 100% honest to yourself in your journal for it to be effective. You're the only one who will know what's in the journal, so do right by yourself and write down everything truthfully. When you are trying to control your drinking habits, going out to the bars or hanging out with people who drink a lot is a surefire way to feel pressured into keeping up with others. Try to avoid going out by inviting people over to your place instead, or suggest an alternative to the bars to meet up. Coffee shops, shopping centers, arcades, natural parks and trails, and the "downtown" area of your city have plenty of space to stretch out and be with your friends without the pressure of drinking. While it is great to limit your alcohol intake to the recommended amount each day, it is even better if you are able to take a full day away from the bottle every now and again. Choose 1 or 2 days every week to avoid alcohol, and you may find that it becomes easier to limit your consumption on days you do decide to have a drink. After having a few days without any drinks, set a date in the future where you will abstain from alcohol for a week straight. This will reveal to you how your emotions and physical appearance change under the influence, and will help you to cut down in the future. Cutting down on drinking is a difficult task, especially if you have been heavily drinking for a while. Simply reducing your intake to the recommended daily amount can make you feel emotionally unwell, but if you ever have the urge to go over your limit, remind yourself of why you are cutting down and find someone you trust to talk it out with.
Summary: Determine the alcohol content of beverages you choose to drink. Keep a journal of your daily drinking habits. Avoid social situations where you would be pressured to drink. Plan out days each week where you will not drink any alcohol. Prepare to deal with urges by reminding yourself of your goals and talking to others.
