6.4 Integral Applications
If the acceleration is constant, then force is constant also.
Units are always important.
Force is in newton where from .
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:
