Physics Questions

In physics, we know that the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Hence, An object that has kinetic energy must be in motion i.e, moving.

Heat always flows from a body at higher temperature to a body at a lower temperature.

Although  the image is inverted the mental interpretation of the effect on the retina is as though it is erect
