first of all, you'll have to tell abt the type of motion you are dealing with.
whether its linear or rotational or simple harmonic.
In a simple harmonic system, K.E and P.E becomes when the body has a displacement = A/(root of 2), where A=amplitude.

∙ 10y agoWhen an object is stationary in a plane, (no hill or slope) then potential energy and kinetic energy are equal. Following the case, if an object is stationary at the top of a hill, it has stored energy (potential energy) due to gravitational attraction, as the force of gravity attracts the object towards the ground and once the object gets some kind of motion, all those potential energy will change to kinetic energy.

Actually, the Object CAN be moving, but it is moving Parallel to its Reference Frame, and at a Constant Velocity.

according to some grand omniscient higher observer.
Under those conditions, the observer would say that the object is "at rest"
and its kinetic energy is zero, in his particular little world.

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.
Is absolute zero the point at which a substance has minimal thermal energy?
Yes! Absolute zero has minimal kinetic energy.
What is the temperature at which no more energy can be removed from matter?
Absolute zero. On the Kelvin scale of heat measurement, 0K is the point at which no more energy can be removed or −273.15°C / −459.67°F. There is not enough energy there at 0K to transfer any movement from the substance to another substance.
Why velocity of a mass attached to a spring is maximum at mean positions and zero at extreme positions?
This can easily be understood with conservation of energy. Assuming that no energy is lost, potential energy is continuously converted to kinetic energy, and vice versa. At the mean position, the potential energy is zero, therefore the kinetic energy (and hence the velocity) is at maximum.This can easily be understood with conservation of energy.

An object that has NO kinetic energy must be?
An object with zero kinetic energy is at rest. However, since reference frames are relative, the calculation of kinetic energy is done with reference to an arbitrary point.
When does zero kinetic energy occur?
kinetic energy is zero when the body is at rest.
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....
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.

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).
What is kinetic energy plus potential?
It equals basic energy
Kinetic energy divided by potential energy equals?

Would a book on a table one meter above the floor have more kinetic energy than a book resting on a floor?
No. Kinetic energy would be zero in both cases. The book in the higher position has more potential energy.No. Kinetic energy would be zero in both cases.

What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
Is absolute zero the point at which a substance has minimal thermal energy?
