When the velocity is doubled by what factor is its momentum changed?

Momentum also increases by the factor of 2 .


When the mass of a moving object is doubled with no change in speed. by which factor is its momentum changed?

Momentum is mass times velocity - therefore, momentum would also double.


What would be the momentum if the velocity and mass were doubled?

Momentum is proportional to both velocity and mass; therefore in this case, momentum would increase by a factor of 2 x 2 = 4.


Relatinship between velocity and momentum of the object?

With any two of the three values of velocity, momentum and mass, the third can easily be calculated. (Momentum) = (Velocity) x (Mass) If you were to multiply the velocity by some factor, the momentum would also be multiplied by that same factor. These are directly proportional.


Is mass a factor in calculating momentum?

yes momentum is mass times velocity


If the velocity of an object is doubled the kinetic energy is?

It will increase by a factor of 4 (2 squared).


What are 2 factor does momentum depend on?

By definition p=mv: momentum = mass * velocity (speed if you don't care about direction)


The speed of a moving object is doubled with no change in mass. By what factor is its kinetic energy changed?

KE=(1/2)(m)(v2) since speed is absolute value of velocity, but velocity is squared, (speed)2=(velocity)2 then doubling the speed with no change in mass will change the KE by a factor of; 22=4


Factor that affects an object's momentum?

Mass and Velocity(speed) affects an object's momentum. The object's weight doesn't. Spacecraft have tons of momentum in space, although they have almost no weight there.


What happens to the pressure gauge reading if the flow velocity is increased?

From the Bernoulli equation, pressure drop increases with the square of velocity. So if the velocity is doubled the pressure drop will increase by a factor of four.


What does it mean to say momentum is directly proportional to mass and velocity?

Being proportional means that if you change one by a given factor, the other will change by that factor as well. Being proprtional to both means it is proportional to their product, i.e. momentum equals mass times velocity, p = mv.
