Force is defined as mass times acceleration. And in SI units, mass is in units of kilograms and
\n" ); document.write( "a generally accepted figure for the force of gravity is 9.8 meters per second^2.
\n" ); document.write( ".
\n" ); document.write( "In this problem, the total mass acting on the wire is 70 + 82 + 20 + 17 = 189 kilograms.
\n" ); document.write( ".
\n" ); document.write( "Substituting this and the acceleration due to gravity into the Force equation results in:
\n" ); document.write( ".
\n" ); document.write( "F = m*a = 189 * 9.8 = 1852.2 kg/m/sec^2
\n" ); document.write( ".
\n" ); document.write( "and since a Newton is equal to a kg/m/sec^2, the answer is
\n" ); document.write( ".
\n" ); document.write( "1852.2 Newtons
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the relationship between mass (kilograms) and Force (Newtons). \n" ); document.write( "
