Kinetic energy is the energy of motion.
The formula for kinetic energy is given as
KE = (0.5) m v²
where m = mass of object , v = speed of object.
an object having some speed and mass will have kinetic energy while an object at rest will not have any kinetic energy since the speed of object at rest is zero.
Since at rest speed is zero. an object has kinetic energy only when it is in motion.
If the question is true or false then the answer is true

MARK ME BRAINLIEST THANKS MY ANSWER PLEASE
Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
The less valence electrons the more reactive the element is.
