Document Summary
If the acceleration is constant, then force is constant also. In the us metric system, unit for force is in pound (lb). In the international metric system, water density is. In the us metric system, it is . Since the denominator unit represents volume, it must be multiplied by the volume of the matching unit to get the force. Total work done to move an object over the distance of [ ] is expressed as: Given the force function of , work represents the area under the curve . If force is in newton and distance in meters, work is in newton-meter (ie. joule ) from. In the us metric system, work is in foot-pound . Force needed to stretch a spring by units beyond its natural length: , where is the spring constant of positive value. Springs are small in size, so the lengths are usually given in cm or inches.
