Measurement of Elastic Constant of Spiral Spring, and Earth's Gravitational Intensity

K (N/m) is the spring (elastic) constant.A mass m is placed on the spring, acting on the mass gravitational field of the Earth.Of uncertainty in this value of the spring constant of spring using max / min gradients.The absolute uncertainty in this value of the spring constant of spring.The experimental value and absolute uncertainty spring constant.Clearly, the source of greatest error in the experiment is in the measurement of the period.F (N) , in the spring is proportional to the extension.The measurement results of load mass and reading on ruler.Table 2. The measurement results of total mass of load and time of 10 complete oscillations.Table 3. Measurement error and calculations.
