Simple Pendulum
INTRODUCTION
Simple Pendulum
A simple pendulum consists of a large mass (bob) suspended by a light string from a rigid support
(Figure 1). The length of the string is large compared to the dimensions of the bob. A stationary
pendulum has i
Acceleration of Gravity
INTRODUCTION
An object in free fall has a downward acceleration of magnitude, g, where g = 9.80m/s2 . The
acceleration is produced by the gravitational force that the earth exerts on the object. Applying

The Force Table:
The force table is a piece of equipment that allows us to determine the resultant of force
vectors experimentally. The circumference of the table is adjusted in degrees. The
