What will happen to the momentum of a body whose velocity is doubled?

Momentum = mass x velocity.
So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.

What can be said of an object whose mass stays constant but its momentum is changing?
MOMENTUM IS MASS X VELOCITY, SO ITS VELOCITY IS CHANGING
How velocity changes with time?
It changes if a force is applied to the body whose velocity is being measured.
Describe the motion of a bus whose acceleration is 0 but whose speed is not 0.?
The bus is in steady motion along a straight line at a constant velocity.
How velocity different from speed?
Velocity is acceleration and direction put together. The velocity of something changes if either acceleration or direction changes. Speed is just the average MPH measure. Velocity is not acceleration and direction put together. In that kind of description, velocity is is speed and direction put together. Velocity is a vector, whose size is the speed.
Under what condition a body whose velocity is directed towards east has an acceleration directed west?
In circular motion an object accelerates towards the radius of the circle but its velocity is unchanged

What is variable velocity?
variable velocity can be defined as a moving body whose velocity changes with time
How velocity changes with time?
It changes if a force is applied to the body whose velocity is being measured.
A boat whose velocity through the water is 14 kmh is moving in a river whose current is 6 kmin relative to the riverbed The velocity of the boat relative to the riverbed must be between?
13.9 km hr
What is the magnitude of force acting on a body moving with constant velocity?
Certainly not. An object has momentum on account of its motion, which depends on its mass and its velocity. Force may be involved in the object's motion, but doesn't need to be. If we let the discussion become somewhat flabby, we can imagine a constant force applied to an object, and asked what happens to the object's momentum. An object with a constant force acting on it exhibits constant acceleration in the direction of the force. In that situation, the object's speed, and therefore its momentum, are proportional to the time the force continues to act on it.
What is a velocity potential?
A velocity potential is a scalar function whose gradient is equal to the velocity of the fluid at that point. If a fluid is incompressible and has zero viscosity (an ideal fluid) its velocity as a function of position can always be described by a velocity potential. For a real fluid this is not generally possible.
What units do you measure force in?
Force is measured as the rate that the momentum of an object changes based on the mass of the object whose momentum is being changed. The unit used is Newtons, and is given as a single kilogram increasing in momentum by 1 meter per second per second.
What is indicated by a velocity time graph that crosses the x axis?
That the object whose velocity is being graphed has reversed direction (and is now going in the opposite direction). Velocity is a vector quantity: it has both magnitude and direction.
Describe the motion of a bus whose acceleration is 0 but whose speed is not 0.?
The bus is in steady motion along a straight line at a constant velocity.

What are tachions?
hypothetical particles whose velocity exceeds the speed of light also spelled "tachyons"
What is better getting 100000 at once or getting a penny whose sum is doubled everyday for 31 days?
Take the penny a day doubled every day. The sum would be almost 43,000,000.
