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
KE = 1/2 mv2 let m be initial mass and v be initial velocity KE= 1/2 (m/3) (4v)2 = 1/2 x m x1/3 x 16v2 = 1/2 (5 1/3) mv2 Therefore factor of increase is 5 1/3
Momentum is mass times velocity - therefore, momentum would also double.
variable
When something is variable, it means it can and does change, sometimes a lot. A variable is a factor or condition in an experiment that can change. Some are changed by you, some are changed by other variables and some are kept the same by you.
The dependent variable is the variable that can change in an experiment.
A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.
no, a dependant variable is.
It doubles. Momentum (p) is the product of velocity (v) and mass (m). For a given mass, if you double the velocity, you'll double the momentum. Velocity and momentum are said to be directly proportional. p = m x v
The frequency is the reciprocal of the period. If the period is doubled, the frequency will change by a factor of 1/2.
It is doubled.
The area increases by a factor of 4.
Stefan-Boltzmann equation, power is proportional to T4, so if T is doubled power increases by a factor of 16.

variable
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.
variable
If the magnitude of each of two charges is doubled, then the direction of the force between them doesn't change, but its magnitude increases by a factor of 4.
The volume of any solid is proportional to each of its three dimensions.So if one dimension is doubled, the volume increases by the factor of 21 = 2 .And if two dimensions are doubled, the volume increases by the factor of 22 = 4 .And if each dimension is doubled, the volume increases by the factor of 23 = 8.
The factor changed is the independant varible, the thing that the scientist can change each time they run the experiment.
