Is absolute zero the point at which a substance has minimal thermal energy?
Yes! Absolute zero has minimal kinetic energy.
When does zero kinetic energy occur?
kinetic energy is zero when the body is at rest.
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.
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.
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.
What happen to simple pendulum at lowest point of its swing?
At the low point of a swinging pendulum, the type of energy being demonstrated is maximum kinetic energy. It has zero potential energy at this point of the swing.
How does a yo yo transfer potential energy to kinetic energy and back again as it moves up and down its string?
Before a yo yo is released, it has maximum potential energy and zero kinetic energy. As the yo yo goes down the string, its kinetic energy increases and it potential energy decreases. When the yo yo reaches the bottom of the string it has maximum kinetic energy and zero potential energy. As the yo yo goes back up the string, its kinetic energy decreases and potential energy increases until the yo yo reaches the top of the string, at which point kinetic energy is zero and potential energy is at its maximum.
Does a person standing in motionless in the aisle of a moving bus have kinetic energy?
Velocity depends on the point of view, or as they say in physics, on the "frame of reference". The amount of kinetic energy depends on velocity, and therefore, it also depends on the frame of reference.From the point of view of someone else who is also standing in the bus, such as person would have zero velocity and zero kinetic energy. From the point of view of one who watches the bus from the outside (standing still, near the road for example), the velocity, and therefore also the kinetic energy, of the person being considered will be non-zero.

Is temperature a relative or absolute quantity explain.?
Temperature is an absolute quantity because they are based on the kinetic energy of molecules. The point absolute zero is the point where there is no kinetic energy among molecules and this point is 0 K, -273.15 C, or -459.67 F.
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....
Where the kinetic energy and potential energy becomes equal in simple pendulum?
A pendulum oscillates between two stationary points at the ends of its swing, with maximum speed at the center of the swing. So the kinetic energy is highest at the swing center where it is travelling fastest, and drops to zero at the stationary end points. The potential energy does the opposite, being a maximum at the ends and minimum in the center.
