How to Read Values From the Table
The physics reference table contains a ton of useful information, if you know how to read it. Here are some tips to help you navigate this valuable resource:
Units
The table provides the units of measurement for each quantity. Make sure you pay attention to the units, as they tell you what the numbers in the table actually represent. For example, density is given in kg/m^3, so you know the values refer to mass per unit volume.
Constants
The table lists important physical constants like the speed of light, gravitational acceleration, and Planck’s constant. These values are fixed and unchanging. You’ll use them often in calculations and problems.
Conversion Factors
Need to convert miles to kilometers or Celsius to Fahrenheit? The reference table has you covered. It provides conversion factors for commonly used units. Just multiply the quantity you want to convert by the appropriate factor.
Values
The bulk of the table consists of values for various properties and quantities. These include things like the density of copper, the specific heat of water, and the wavelength of light corresponding to a particular frequency. When you need one of these values for a calculation or to look up information, the reference table is the place to find it.
Interpolation
Sometimes the exact value you need isn’t listed in the table. In that case, you can interpolate between two values to estimate it. For example, if you needed the density of a material with a mass of 32 g and the table only listed values for 30 g and 35 g, you could interpolate between those points to determine the density for 32 g. Interpolation is a useful skill that allows you to extract more information from the table.
The physics reference table puts a wealth of knowledge at your fingertips. With regular use, you’ll get better at navigating the table and become adept at finding whatever values or information you need. The key is just knowing how to make the most of this helpful resource.
Real-World Examples Using the Reference Table
The physics reference table contains a wealth of information that applies to real-world situations. Here are a few examples of how the table can be used in everyday life:
Calculating the Energy Used to Power Your Home
The reference table provides a list of energy equivalents that can help you calculate how much energy you use at home. For example, if your electric bill says you used 1,000 kilowatt-hours (kWh) of energy last month, you can convert that to joules using the table. 1 kWh = 3,600,000 joules. So 1,000 kWh = 3,600,000,000 joules of energy used in your home last month! Using the table, you can also convert that energy usage into BTUs, calories, or electron volts.
Figuring Out How Much Force is Exerted
Did you ever wonder how much force is exerted when you push open a door or lift a heavy box? You can use Newton’s second law (F=ma) and values from the reference table to calculate it. For example, if you push open a door with a mass of 20 kilograms and cause it to accelerate at 2 meters/second^2, the force exerted is:
F=ma
F=20kg x 2m/s^2 = 40 N
So you exerted 40 newtons of force to push open that door. The reference table provides the conversions to calculate forces in newtons for any masses and accelerations.
Estimating the Final Speed of a Rolling Object
If you give a ball a push to get it rolling, you can use the reference table to estimate its final speed. Assume you push the 0.5 kg ball with 10 newtons of force. Using F=ma, the acceleration is:
a = F/m = 10N / 0.5kg = 20 m/s^2
The final speed depends on how long it accelerates. If it accelerates for 2 seconds, the final speed can be calculated using the kinematic equation v=at.
v=20m/s^2 x 2s = 40 m/s
So after 2 seconds, the 0.5 kg ball you pushed will be traveling at around 40 meters per second. The reference table provides all the values needed for these types of kinematic calculations.
Tips for Memorizing Key Values
Memorizing the values in the physics reference table can seem like an overwhelming task. Here are some tips to help make it manageable:
Focus on the numbers you’ll use most often
Prioritize memorizing the values you know you’ll frequently use in problems and calculations, like the speed of light, gravitational constant, and electron mass. The rest you can always look up as needed.
Group similar values together
Try memorizing values with similar units or in the same table section together. For example, memorize the proton, neutron and electron masses as a set. Or memorize all the derived SI units like newtons, pascals and joules together. This can make them easier to remember.
Use mnemonics
Create mnemonics, like rhymes, acronyms, songs or other tricks to help memorize values. For example, “King Phillip Came Over For Good Spaghetti” to memorize the order of taxonomy: Kingdom, Phylum, Class, Order, Family, Genus, Species. Or “Some Lovers Try Positions That They Can’t Handle” to memorize the electromagnetic spectrum: Super Low Frequencies, Radio Frequencies, Microwaves, Infrared, Visible Light, Ultraviolet, X-rays, Gamma Rays.
Practice regularly
The more you practice recalling the values, the more they will stick in your memory. Flip through the physics reference table for a few minutes each day, testing yourself on different sections. Flashcards are also great for memorization practice.
Don’t worry about precision
You don’t need to memorize values to a high degree of precision, especially constants with many digits. Round to 2-3 significant figures for most values. Your teacher will specify if more precision is needed for a particular problem.
With regular practice, the most important values in the physics reference table will become second nature. Let me know if you have any other questions!
