Step-by-Step Solution:
Step 1 of 3

Work and Power Work ● When a force acts on an object, i does work on the object. ○ W=F*d ○ Work = Force * isplacement ■ The force must be PARALLEL to the displacement ● Measured in Joules (Newton­meter) ● Ifthere is an angle, only the cosine of the angle times the force is what i doing the work. Sine of the angle times the force is doing nothing. ● Ifsomething lides on a amp, W=mgdsinθ ○ Decreasing the angle will decrease the ork ● Ifthere is more than one force acting on an object, we can find the work done by each force then determine the ne
