What else can I help you with?
Is total energy of revolving electron in an atom zero?
actually total energy is the sum of potential energy and kinetic energy....potential energy= -2*kinetic energy . By using this relation you will get that sum of potential and kinetic energy is equal to the magnitude of kinetic energy and it is less than zero...hope this will be enough for you....
Why if total momentum is zero but kinetic energy is not equal to zero?
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.
When does zero kinetic energy occur?
kinetic energy is zero when the body is at rest.
Is there a connection between absolute zero and potential and kinetic energy?
Absolute zero is the (theoretical) limit at which all molecular movement stops (that means that the total kinetic energy of all the molecules in the substance being cooled to absolute zero becomes zero).
What point in the ride is the kinetic energy of the car zero?
The kinetic energy of the car becomes zero when the car halts. If it halts on top of a hill, the energy changes to potential energy.
Can you have kinetic energy without momentum?
We don't think you can. Here's our reasoning: -- Kinetic energy of an object is [(1/2)(mass)(speed)2]. If kinetic energy is not zero, then mass can't be zero, and speed can't be zero either. -- Momentum of the object is [(mass)(speed)]. If mass isn't zero and speed isn't zero, then momentum isn't zero.
What is the sum of potential and and Kinetic energy?
The sum of potential and kinetic energy is the total mechanical energy of an object. This total energy remains constant in the absence of external forces, according to the principle of conservation of mechanical energy.
Example for a body with zero momentum and some kinetic energy?
No solution. Zero momentum (MV) means either zero mass or zero velocity. Either one results in zero kinetic energy (1/2 MV2).
Can a body have kinetic energy without having momentum?
Momentum = (mass) x (speed) Kinetic Energy = 1/2 (mass) x (speed)2 It looks like the only way a body can have zero momentum is to have either zero mass or else zero speed, and if either of those is zero, then that makes the KE also zero as well, too. So the answer to the question is apparently: no.
Which law of thermodynamics states that it is impossible to reach absolute zero?
An object can never reach absolute zero in kinetic terms because there is never a total lack of kinetic energy, molecules are always moving.
What type of collision is kinetic energy is conserved?
An elastic collision conserves kinetic energy. In this type of collision, the total kinetic energy before the collision is equal to the total kinetic energy after the collision.
Is kinetic energy conserved in an elastic collision?
Yes, kinetic energy is conserved in an elastic collision, meaning the total kinetic energy before the collision is equal to the total kinetic energy after the collision.
