When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How much work would it take to push a # 5 kg # weight up a # 7 m # plane that is at an incline of # pi / 4 #?
- The force applied against an object moving horizontally on a linear path is described by #F(x)=4e^x+ 1/x #. By how much does the object's kinetic energy change as the object moves from # x in [ 1, 3 ]#?
- A force field is described by #<F_x,F_y,F_z> = < xy , 2z-y +x, 2y -z > #. Is this force field conservative?
- A balanced lever has two weights on it, the first with mass #12 kg # and the second with mass #4 kg#. If the first weight is # 7 m# from the fulcrum, how far is the second weight from the fulcrum?
- If an object with a mass of #15 kg # changes speed from #25m/s# to #14 m/s#, by how much does its kinetic energy change?
