What exactly is kinetic energy, if it is in the same units as work? What is the difference between the two?

Kinetic energy is a quantity possessed by the body, due to its velocity. It is always positive. Work is in an exchange term that will affect the KE of the body. Work can be a positive transfer and it will add KE to the body. Work can be a negative transfer that will take KE from the body. It's a bit like your mass: it is always positive, but it can increase with positive intakes of food or decrease with body waste disposal (incl. breathing).

you can calculate them by : Kinetic energy :\[k=(1/2)*m*v^2\] m=mass(Kg) v=velocity(meter/second) Work : \[W= F.d= F*d*\cos \theta\] d=distance(meter) F=Force(Newton) Yes they are same in unit, they are both Joule, The difference is clear I think ... ! Work is work and Energy is the ablity to do a work. Did you got it ... ?! I'll be happy to answer, if you have any questions ... ! ;-)

and \[\theta \] is the angel between the force and distance vectors ...
