The kinetic energy would be quadrupled, and the momentum would be doubled.

How will the momentum of a body changes if its Kinetic energy is doubled?
Let's see. Mass constant. 625000 Joules = 1/2(500 kg)V2 1250000 Joules = 500V2 2500 = V2 50 meters/second = velocity ==================================== The velocity doubles if KE doubles.
If an objects velocity is doubled what happens to its inertia?
assuming its not starting at zero, if an object velocity is doubled, its kinetic energy (KE) is four times. If its trebled , its KE is nine times equation : KE = (m*v^2)/2 joules m=mass v=velocity
How does kinetic energy change when the momentum is doubled?
energy is quadrupled
Does kinetic energy increase with speed and time?
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
When velocity of body is doubled?
momentum is doubled, kinetic energy is quadrupled
What happens to kinetic energy of an object if the velocity is doubled?
If the speed of an object doubles, its kinetic energy quadruples. This is because velocity is squared in the formula for kinetic energy.
When the speed of body is doubled kinetic energy becomes?
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
What happens to an objects kinetic energy when the velocity is doubled?
toaster
If the velocity of an object is doubled its kinetic energy is multiplied by?
since kinetic energy is proportional to the square of velocity it is multiplied by 2 x 2 which is 4
What will happen to kinetic energy of the object if its mass is doubled but the velocity remains the same?
It doubles.
What happens when the velocity of the Earth is doubled?
If the velocity of Earth were to double, it would have 4 times the kinetic energy. Twice the current kinetic energy would already be enough to catapult the Earth away from the Sun - never to return.
What will happen to the KE of an object if its mass is doubled but the velocity remains the same?
Twice the mass --> twice the kinetic energy.
What will happen to kinetic energy if the velocity is doubled but the mass remains the same?
If the velocity is doubled, then the kinetic energy increases by 4 times
If the speed of a moving object is doubled the kinetic energy of the object is?
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.
How will the momentum of a body changes if its Kinetic energy is doubled?
Let's see. Mass constant. 625000 Joules = 1/2(500 kg)V2 1250000 Joules = 500V2 2500 = V2 50 meters/second = velocity ==================================== The velocity doubles if KE doubles.
2009 tnpsc group 2 question paper?
when the speed of a body is doubled its kinetic energy becomes kinetic energy = 1\2 mv^2 speed = velocity kinetic energy = 1\2 m (2)^2 kinetic energy = 2 m so hence the answer is kinetic energy is quadrapole.
