When 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.
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.
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.
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.

A gas, or any matter, would have zero kinetic energy when its temperature reaches absolute zero, zero degrees Kelvin. While such matter is theoretically possible, it has never been observed since any observations of such matter would require some sort of energy transfer, which would be impossible for a substance with zero kinetic energy In practically all these kind of questions the unspoken implication is that we are talking of thermal kinetic energy. Even at absolute zero, there would be kinetic energy due to the earth's rotation, its movement round the sun, the movement of the sun and of the galaxy, whatever that implies about relativity and expansion of space and so on. Even thermal motions have this nasty little hiccup, known as the zero point motion.
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.
kinetic energy is zero when the body is at rest.
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.

No solution. Zero momentum (MV) means either zero mass or zero velocity. Either one results in zero kinetic energy (1/2 MV2).
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.

zero mass = zero energy

At 0 Kelvin, all molecular motion stops, so the kinetic energy of the vapor molecules would be zero. Therefore, the kinetic energy of the vapor would be reduced to 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....
