A numerical value for the acceleration due to gravity g on straigh line = 8.665
What is Straight Line?
Simply put, a straight line is a line devoid of bends. A straight line is one that has no curves and continues to infinity on both sides.
we need a table calculation for that see the attachment 1
vertical axis = l cm
horizontal axis = T²(sec²)
slope from the graph
= l/T²
= 0.2197
So, g = 4 T² * l /T²
= 4 * (3.14)² * 0.2147
g = 8.6646
g = 8.665 m/sec²
The acceleration caused by gravity is expressed numerically as g on a straight line = 8.665.
