Question

Define:

(i) Rigidity,(ii) Kinetic energy.​

Answer 1

Answer:

rigidiry-a resistance to unbending or inflexibility. ex solids are rigid as they cannot be bent easily and are not flexible except a few exception

kinetic energy- a form of energy measured in joules and its formula is 1/2mv^2

Answer 2

1) Rigidity

Rigidity means no bending — in that case, of the rules. Objects and substances can have rigidity as well, if they literally won't bend. Rigidity means about the same thing as inflexibility, another word that describes rock-solid, unyielding people and substances.

2)Kinetic energy

energy which a body possesses by virtue of being in motion.

"energy above that needed to ionize the molecule is carried away as kinetic energy of the electron ejected"
