State whether True or False. (i) Work is said to be done when a force is applied, even if the object does not move. (ii) Lifting a bucket vertically upward results in positive work done on the bucket. (iii) The SI unit for both work and energy is joule (J). (iv) A motionless stretched rubber band has kinetic energy. (v) Energy can change from one form to another.

Statements (ii), (iii) and (v) are True, while (i) and (iv) are False. Work requires displacement and a motionless stretched rubber band stores potential energy rather than possessing kinetic energy due to lack of motion.
