No, not at all. Kinetic energy is energy related to movement - any moving object has kinetic energy; at low (non-relativistic) speeds, the kinetic energy is calculated as 0.5 x mass x velocity squared.No, not at all.

an object has no kinetic energy if it is not moving
an object has no kinetic energy if it is not moving
It has a non-zero momentum. It also has non-zero kinetic energy.
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
yes it does mean in motion
The word kinetic has its roots in the Greekword Kinesis which means motion.

Kinetic energy is energy related to movement or motion, if that's what you mean.
More speed means more kinetic energy.More specifically, the kinetic energy is proportional to the square of the speed. (This is for non-relativistic speeds.)
