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?

What will happen to kinetic energy of the object if its mass is doubled but the velocity remains the same?

It doubles.


A moving car has kinetic energy If it speeds up until it is going four times faster than before...how much kinetic energy does it have in comparison?

Kinetic energy is proportional to velocity2, so if velocity is multiplied by four the kinetic energy is multiplied by sixteen


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.


If the velocity of a moving body is doubled what does this do to kinetic energy and the momentun of the body?

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


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 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


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.


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.
