The relation between kinetic energy is proportional to the square of velocity. Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase (so velocity remains well below the speed of light), then its velocity is doubled. If the velocity is doubled then the kinetic energy increases by the square of 2, or four time.
kinetic energy= half mass multiplied by velocity square (KE=1/2mv2)
if velocity is doubled, then KE=1/2mass multiply by 2velocity square
then, 1/4 KE= 1/2 mass velocity square
so it can be deduced that if velocity is doubled of an object, then its kinetic energy will decrease by 4 times.
Increased. Formula is E= Mass x velocity squared. Doubling the velocity has a disproportionate effect on energy because of squaring. 1 grain object at 10 ft per second= 1x 10 squared- 100. 1 grain at 20 fps, 1 x 20 squared- 400 1x 40 gr squared- 1600 etc. Rather steep curve there.
Its kinetic energy is quadupled - KE = (1/2)mv2. If you multiply v by two, then KE = (1/2)m(2v)2, or KE = (1/2)m(4)v2, or KE = 2mv2, 4 times the initial KE.
It will increase by a factor of 4 (2 squared).
When mass of object is doubled, then the potential energy will also double.

an object has no kinetic energy if it is not moving
An object has kinetic energy when it is moving and not when it is at rest. When it is at rest it has potential energy.
When an object is moving, it is called kinetic energy.
kinetic energy is motion energy, therefore any object that is moving possesses kinetic energy.

Kinetic energy
Kinetic energy is when it's moving. Potential energy is when the object is motionless.
Any moving object has kinetic energy.
Any moving object has kinetic energy.
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
