    (b) Use the table to determine the value of g. (Note: The
    units for g are feet per second per second.)

    • logan edwards Simple Pendulum Gravity is responsible for an object
      falling toward Earth. The farther the object falls, the faster
      it is moving when it hits the ground. For each second that
      an object falls, its speed increases by a constant amount,
      called the acceleration due to gravity, denoted g. One way
      to calculate the value of g is to use a simple pendulum.

    • logan edwards Thank you can you help me with this?
      The time T for a pendulum to swing back and forth
      once is called its period and is given by
      where L equals the length of the pendulum. The table lists
      the periods of pendulums with different lengths.

    • andy chuks Hi Logan I will give you a guide on how you can solve this problem first know that
      period T = 2pi x (L/g)^-2
      (L is the length of pendulum, pi is 3.142, and g is the acceleration of gravity)

      From the above equation making g
      T^2 = (4pi^2 x L)/g
      T^2 /L = 4pi^2/g

      From the above you have values for L and T,
      create a table of values L, T, T^2
      using the values of T^2 and L plot a graph of T^2 verses L and find the slope of the graph.
      The slope of the graph is equal to [4(pi)^2]/g

      Therefore making g subject formula your g is = [4(pi)^2]/Slope
