Question

Can a body have energy without having momentum ? Give reason

Answer 1

Yes, something can have energy without having momentum.

Momentum is defined as the mass of an object times its velocity. To have momentum, an object must be moving.

There are several types of energy such as kinetic energy, potential energy, and internal energy.

Kinetic energy is the energy of movement. If something isn't moving, it doesn't possess kinetic energy.

There are a few types of potential energy including chemical, gravitational, and nuclear.

Internal energy is generally thought of as the motion of the molecules of an object.

A rock, at rest, hanging half off of the edge of a cliff, has gravitational potential energy and internal energy. It has gravitational potential energy because it has the potential to fall to the ground beneath the cliff's edge. It has internal energy because the molecules in the rock are vibrating because its temperature is greater than 0 Kelvin (absolute zero). Since the rock possesses energy but isn't moving, it is possible for something to have energy without momentum.

Answer 2

Answer:The outer layer of fabric does get hotter because the black color absorbs more heat. ... A black body absorbs almost all the wavelengths of lightreceived by it(hence the color) and awhite colored body on the other hand reflects all(or most of) the wavelengths of light falling on it
