Objective:

Intro:

Apparatus: The following materials needed for this lab are: ruler, balance, stopwatch, meter stick, hollow copper cylinder, wood block, physics textbook, dollar bill, and ball (5cm-10cm).

Procedure:

Part 1: Use the balance to measure the mass of a meter stick, ball, and physics book.

Guess the mass of the meter stick in grams.

Measure the mass of the meter stick to the nearest 0.1 gram.

Guess the mass of the ball

Measure the mass of the ball to the nearest 0.1 gram.

Guess the mass of the physics textbook

Measure the mass of the textbook.

Part 2: Use a meter stick or ruler to measure the length and width of the physics textbook in centimeters to the nearest 0.1 cm. Calculate the area of the textbook surface in cm squared and m squared. Calculate the number of significant digits in the length, width, and area of the textbook.

Part 3: Measure the mass and dimensions of the wooden block

Measure the mass of the block to the nearest 0.1 g.

Use a ruler to measure length, width, and height of the wooden block to the nearest 0.1 cm.

Calculate the volume of the wooden block.

Determine the number of significant digits of the volume of the wooden block.

Calculate the density of the wooden block.

Calculate the percent error in the density of the wooden block.

Discuss the possible sources of error in the measurement.

Part 4: Measure the diameters of the copper tube.

Use a ruler to estimate the inner and outer diameters of the copper tube to the nearest 0.1 cm.

Discuss possible sources of errors in the measurements.

Use the Caliper to measure the inner and outer diameters of the copper tube to the nearest 0.1 cm.

Measure the height of the copper to the nearest 0.01 cm.

Using the digital balance measure the copper tube.

Calculate the volume and density of the copper tube.

Determine the number of significant digits of the volume of the copper tube.

Calculate the percent error in the density of the copper.
