How to find work when given force and time

answer:

work can be calculated with the equation: work = force × distance.

the si unit for work is the joule (j), or newton • meter (n • m).

the equation for work can be rearranged to find force or distance if the other variables are known.

the work is calculated by multiplying the force by the amount of movement of an object (w = f * d). a force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. a newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.

explanation:

answer:

1. work can be calculated with the equation: work = force × distance.

2. the si unit for work is the joule (j), or newton • meter (n • m).

3. the equation for work can be rearranged to find force or distance if the         other variables are known.

plz mark me as brainliest if this : )

half of a circle

explanation:

the arrow and the top of the circle is matching together. it is not a polygon because a polygon would always be the same shape. therefore, an half of a circle is called semicircle so you would find the radius of it.
