Gravity lab using mass and force meters

Extracts from this document...


Cem Ozer 11H g Using Masses and Force Meters Lab Report AIM Our aim is to find the gravitational field strength for this area. INTRODUCTION Gravitational field strength, g, is the force acting on a mass at a point in a gravitational field. The units of g are Nkg-1 or ms-2. Weight, W, relates to g and mass, m by: W = mg or g = W/m If we assess our masses and the forces acting on them (correctly), afterwards put them on a weight vs. ...read more.


3. We repeated the process by adding another 100g mass each turn. 4. We finished the process and formed a data table. 5. Then we added an average point to our data table. 6. Later, we graphed our data’s and drew our min, max and best lines. 7. We calculated our slopes. Independent Variable: 1. Mass Dependent Variable: 1. Weight Controlled Variables: 1. Place 2. Temperature DATA COLLECTION AND PROCESSING RAW DATA Mass (kg) ±1% 0.100 0.200 0.300 0.400 0.500 0.600 0.700 0.800 0.900 1.000 0.550 Weight (N) ...read more.


CONCLUSION AND EVALUATION g = 9.9 Nkg-1 ± 0.4 Absolute Error = I accepted – measured I = I 9.821 – 9.9 I = 0.8% accepted 9.821 The range of our experimental value includes the accepted value, so it is accurate, but not precise. The 0.8 % difference between our measured and accepted value might be caused from the misuse of the masses or the loosening of the spring in the force meter. The source of our real value is from the “ Physics IB Year 11, g Using Masses and Force Meters” lab sheet. It is known that TUBITAK has measured it. ...read more.
