The square of 2 is 4. So, if the velocity doubles, the energy increases by a factor of 4.

since, kinetic energy is given by the relation, k= mv2/2
velocity, v= (2km)1/2
If we double the kinetic energy (only) i.e. k, =2k, mass remaining the same, then the new velocity can be obtained by the above relation as,
v, = (2k,m)1/2 =(2*2k*m)1/2 =(2km)1/2 *(2)1/2 = v*21/2
i.e. v'/v = (2)1/2
==================================
Thank you. The presentation is breathtaking in its erudition and its specificity.
The answer to the question is:
In order to double kinetic energy, you have to increase the speed
(magnitude of velocity) by 41.4 percent.

∙ 12y agoKinetic energy= 1/2 mv2
So when v is doubled, kinetic energy increases by 22, that is by 4 times.
Wiki User
∙ 11y agoThe Kinetic Energy would increase by a factor of 4, since : KE = 1/2mv^2

∙ 8y agoenergy goes as velocity squared so it will quadruple energy (four times)
Wiki User
∙ 13y agoNo. Kinetic energy is proportional to the square of the speed.
If the speed doubles, the KE increases by (2)2 = 4 times.

What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
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 happens to an objects kinetic energy when the velocity is doubled?

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.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
What happens to an objects kinetic energy as its velocity increases?
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2

What happens when you decrease the velocity of a car?
as you decrease the velocity of a car, you decrease the kinetic energy.
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.
What happens when kinetic energy is absorbed as an object moves toward the earth?
The kinetic energy increases as the velocity increases (KE = 1/2mv2) until terminal velocity is reached, at which point the velocity becomes constant, and kinetic energy will no longer increase. The potential energy and kinetic energy will be at equilibrium, where PE = -KE.
What happens to kinetic energy as velocity increases?
particles speed up.
As kinetic energy increases what happens to mass and velocity?
it speeds up
What happens to speed if kinetic energy halved?
Kinetic energy is determined by mass and velocity. The velocity is halved if you double the original mass, so the kinetic energy stays the same (unless the mass added has the same kinetic energy in the observer's reference frame as the original mass).
