is it the opposite of potential energy?

KENETIC ENERGY:
Kinetic energy is energy that a body possesses as a result of its motion. It is formally defined as the work needed to accelerate a body from rest to its current velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Negative work of the same magnitude would be required to return the body to a state of rest from that velocity.
In simple cases, this work (and thus the kinetic energy) is equal to:
Ek = 1/2 mv2
where m is the object's mass and v is the object's speed.

I"ll put it simple; kinetic energy is the energy of motion. Potential energy is what you could do with the energy you have, but turns to kinetic energy as soon as you move your body.

kinetic energy is the energy an object has because of its motion. a object can not posess kinetic energy if it is not moving. for eg,a car moving with a speed of 10m/s than it has kinetic energy. On the other hand potential energy is the energy an object has due to its position with the ground or its raised position. for eg, water at the top of the dam. sometimes potential energy is related with its condition for eg, a compressed spring or stretched rubberband. this type of energy is elastic potential energy.

kinetic energy is the energy possessed by an object in motion. the greater the velocity the greater the kinetic energy.
potential energy is the energy possessed by an object due to it's location. the higher the object above the sea level the greater its potential energy.

kinetic energy(K or KI) is a form of energy(other forms: light,electrical,sound...). It is possesed by a body due to its motion. If body of mass m is moving with velocity v then,
K=(1/2)m(v*v)
As far as relation of potential energy(PE) is concerned with K,their sum is constant for a body(provided there is no loss of energy ).

Kinetic energy is the ENERGY of MOTION, relative to you.... with whose reference you wish to find it's energy, just like for potential energy we take ground (earth) as the reference level.

Ya.
Energy acquired by a body or a molecule due to it's motion is called as kinetic energy.
But I think this question could be asked in physics category.(For better answers)
However it's not wrong asking it in chemistry in the aspect of molecular kinetic energy ( I think it comes under gaseous and solid states)

its energy possessed by a body due to motion or technically we can say that due to the molecular motion. potential energy is due to position. both are not precise antonyms but we can say that PE is opposite to KE.

quite so in many case KE is derived from PE. KE is the energy of motion and is given by the formula
KE = 0.5xmxvxv
m-mass
v-velocity
x-multiplication sign
KE-kinetic energy

Yes, somehow it is.It's the energy produced by motion.
