Linear Motion Lab

12. Place the magnet on the scale to measure the mass of the object. Record the mass in Data Table 5.

Copied the observations table in our notebook. Then recorded the mass of the beaker using the balance and wrote down the measured mass in the observation

Hold one ball beside the top of the meter stick with the ZERO end touching the table.

6. The mass number is equal to an atom’s number of protons and neutrons added together.

Using Gravitational Force as a Measurement Tool Answer the following questions about the results of this activity. Record your answers in the boxes. Send your completed lab report to your instructor. Dont forget to save your lab report to your computer Activity 1 Record your data from Activity 1 in the boxes below. Enter the data for the sample you used in each trial (5000 rpm, 10000 rpm, etc) in the appropriate columns and the corresponding g-force, number of layers, and position of layers position results. You will need to use the following formula to assist with your laboratory report G-force 0 00001118 x radius of centrifuge arm x (rpm)2 The radius of the centrifuge arm for this instrument is 10 cm. Speed 5000 rpm 10000 rpm 15000 rpm

n the course of your life you will go over numerous sorts of scale. Everything begins from your school lab, where research center scales are utilized to quantify the definite sum and extent of components, to direct a fruitful investigation. On the flip side, you have modern scales e.g. truck scales intended to weight the enormous weight of trucks or transports to ensure they can convey substantial hardware or traveler loads without tilting which can bring about serious mechanical or human misfortune.

2. Lift the spring scale just until the mass is hanging from the scale. Now slowly

1. Place a plastic measuring trough on top of the digital balance, and press the "tare/on" button so that the mass of the trough will be "ignored." The digital balance should read "0.000 g" after this step.

Place the object of your choosing on the triple beam balance's plate. 3. Use the weights to get the other side of the scale on zero to get the mass. 4. Next, place the object in a graduated cylinder filled with

Weigh the nut, the aluminum cup, and the test tube clamp all together. Record the total

Seven various household objects were chosen to measure using a digital gram scale. Each object’s mass was estimated by lab students and recorded in data table 4. A quarter, ball point pen, rubber bulb, large paper clip, green crayon, house key and a copper penny masses were estimated and recorded in data table 4. Each object was placed on the scale individually and its actual measurement was recorded in data table 4. As we started estimating the household objects we were often not correct in our estimations. As we measured more and more objects, we got better in our estimations by comparing objects with known masses and comparing them with the unknown

Using the direct weighing and weighing by difference methods to find weight and mass of chemicals and compounds.

Record the sample mass in your notebook. Remember to record all digits on the balance. Closed toed shoes and goggles are REQUIRED for the lab

If the mass of the reactants are compared to the mass of the products, then the mass will stay the same because the law of conservation of mass states that in any given chemical reaction, the total mass of the reactants equals the total mass of the products.

2. Obtain an evaporating dish and carefully weigh it to the nearest 0.01g on top of the loading scale and record its mass on the data sheet.
