This implies that the spring force is a restoring force. The test was repeated by passing the cord over the left pulley and was attached to the center arm of the bar Figure 5. The right weight hook was removed from the bar. If a resultant force acts on an object then that object can be brought into equilibrium by applying an additional force that exactly balances this resultant.
A linear relationship can be demonstrated if the data points fall along a single straight line. Equipment: Steel ball — contact plate — holding magnet — holding magnet adapter with a release mechanism — electronic stop clock — stand base — rods — scale — connecting leads. The two values should be equal.
Page 4 Section 3 Graphing Physics A Slope is often used to describe the measurement of the steepness, incline, gradient, or grade of a straight line. The straight line should be drawn as near the mean of the all various points as is optimal. The weight hooks was hung from the end holes of the bar see Figure 2.
A spring is an example of elastic materials. The weight of the weight hook and its load, F was recorded. Sometimes finding the center of mass of an object can be challenging, especially if the object has an odd shape. The amount of departure from rest shape is called deformation, the proportion of deformation to original size is called strain.
The distance, d of the hole from the pivot was recorded.
