when the velocity is doubled then its accelration is also doubled.because
a=v/t
The acceleration is zero for a body having constant velocity.
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
momentum is doubled, kinetic energy is quadrupled
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Explain circumstances, in which the velocity acceleration of a body is parallel?
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
The kinetic energy would be quadrupled, and the momentum would be doubled.

Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
The body is not zero, but the sum of all forces on it is. -- "Uniform velocity" means no acceleration. -- Acceleration is force/mass . -- If acceleration is zero, that's an indication that force must be zero.
Explain circumstances, in which the velocity acceleration of a body is parallel?
Firstly, force is equal to mass of the object into it's acceleration, so acceleration is not a force.Next, the change in velocity of a body over time is called acceleration, so yes, acceleration does affecta body's velocity.
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
