Can you please fill out the period on both methods?

Can I get some help with this lab report?

Find the period, K, period T Lab Report 17: Simple Harmonic Motion Purpose of this Lab: Part 1 Method 1 Value of k from method 1: Method 2 Time for ten oscillations Value of k from method 2: l Questions: Calculate your percent difference between your values of R from the two methods. Which method do you think is more accurate? Why? List some possible sources of error, and state how they would have affected your results.

This means that the force moving the body is always in the opposite direction to the direction the body has traveled from its equilibrium position. A simple pendulum system is one in which the mass of the string is assumed to be negligible and the mass of the moving body is assumed to be concentrated at a single point on the end of the string. The motion of a simple pendulum can be described as simple harmonic motion. uncann-n-n;n-uu-.--.."Ian'uuuaau"nu.- The equation of motion for any system gives the position of the moving object as a function of time, x(t). in the force equation F = -kx, the force depends on time because any force can be written as mass times acceleration, and acceleration is the rate of change of velocity with time. For a simple pendulum, the restoring force acting on the mass at the end of the string is the force of gravity. F = -mgsin9 = ma ln the equation above, the force is directly proportional to the sine of the displacement 6, but for very small angles, sin 9 = 9. So, the equation represents SHM, as long as small angles (
