1. Weight – Mass Experiment

2. Purpose To measure the mass of each object in grams using the triple beam balance. To convert the mass in grams to kilograms using 1 Kg= 1000g To calculate the weight using Weight = mass x gravitational acceleration ( 9=-9.8m/s 2 ) To measure the weight force using a spring measurer. To calculate the % error of the measured and calculated values of both mass and weight.

3. Materials Objects Spring scale or force measurer Triple beam balance Calculator

4. Background Information in paragraph format - 2 paragraphs Discuss the difference between weight and mass based on definition and units. Discuss how mass and weight are measured or calculated. Discuss your steps to achieve the purpose List the equations necessary for this experiment. Weight = Mass X g g = 9.8 m/s 2 - acceleration due to gravity

5. Diagram Draw your set up for this experiment. Show how the equipment will be used in this experiment. Label your drawing.

6. Procedures 1.Measure the mass of each object using the triple beam balance or scale.Record. 2.Convert the mass in grams to kilograms. Record. 3.Measure the weight force of each object using a force measurer in Newtons. Record. 4.Verify the weight force by calculation using the equation Weight = mass X -9.8m/s 2.. Record. 5.Calculate the % error using = / calculated weight – measured weight / ------------------------------------------------------ x 100 /calculated weight / Record.
