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.
What happens to an objects kinetic energy when the velocity is doubled?
toaster
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 will happen to kinetic energy of the object if its mass is doubled but the velocity remains the same?
It doubles.

momentum is doubled, kinetic energy is quadrupled

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 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
What happens to the kinetic energy of an object if the speed is multiplied by a factor of 9?
Kinetic energy = 1/2 (mass) (velocity)2That little 2 after the velocity says that the kinetic energy is proportional to thesquare of the velocity.If the speed (magnitude of velocity) is increased by a factor of 9, then the KEis increased by a factor of (9)2 = 81 .
