Measuring the acceleration of gravity with a simple pendulum 1. Practice using a stopwatch or period meter and a ruler to measure the period and length of a simple pendulum; 2. Find the value of the local acceleration of gravity g; 3. Examine the effect of the systematic error of the simple pendulum on the measurement of the acceleration of gravity. Experimental principle A small ball is suspended by an inextensible light line and swung at a very small angle to form a simple pendulum. Suppose the mass of the small ball is , and the distance from its center of mass to the fulcrum o of the pendulum, that is, the length of the pendulum, is . The magnitude of the tangential force acting on the small ball is , and it always points to the equilibrium point . When the angle is very small, then , the magnitude of the tangential force is , and according to Newton\'s second law, the equation of motion of the particle is
