Answer to Question 1

ANS: B
One joule is equal to the force of 1 N acting on 1 kg. A watt is equivalent to 1 J/s. A kilowatt is simply 1000 W. Kinetic energy is energy an object possesses when it is in motion.

Answer to Question 2

ANS: A
Work is performed only when effort or outside forces produce a change in the position of matter.
