Work is defined as how much force on an object times how
much distance the object moves. In physics, work is only being done
when an object is moved a distance by a force. The farther an object
is moved, the more work that is being done. The formula for work is:
Let's say we move a 20 pound object 40 feet. The
work done would be 20 X 40 = 800. Work is defined as
foot-pounds. The work done would be 800 foot-pounds of work.
Scientist also use "erg" and "joule." A joule is
about .738 foot-pounds.
Complete the questions below.
Work is defined as how much
on an object times how much
an object moves.
Scientist use a
,
about .738 foot-pounds to measure work.
The
an object is moved, the more work that is done.
If an object, that weights 30 pounds, is moved 30 feet,
then
foot-pounds of work will be done.
If an object, that weighs 100 pounds, is move 1 foot,
then
foot-pounds of work will be done.
