PLEASE HELP-If a system stores kinetic energy, which choice must be true?

1. The molecules, atoms, and/or subatomic particles must be exerting forces on each.
2. The molecules, atoms, and/or subatomic particles must be at rest.
3. The molecules, atoms, and/or subatomic particles must be within earth’s gravitational field.
4. The molecules, atoms, and/or subatomic particles must be moving.

Answer: Option 4: The molecules, atoms, and/or subatomic particles must be moving.

Explanation: Kinetic energy is the energy related to the movement, and is described by the equation:

K = m/2*v^2

where m is the mass of the object and v is the velocity of the object.

Then, if a system is storing kinetic energy, this means that the molecules, atoms and subatomic particles must have a velocity, this means that they are moving, then the correct option is the fourth one.

If a system stores kinetic energy, the molecules, atoms, and/or subatomic particles must be moving.

What is kinetic energy?

The kinetic energy of an object is the energy possessed by a moving object.

K.E = ¹/₂mv²

where;

  • m is mass of the object
  • v is the velocity of the object

Thus, If a system stores kinetic energy, the molecules, atoms, and/or subatomic particles must be moving. The kinetic energy of particles depends on the velocity of the particles, as the velocity increases, the kinetic energy of the particles increases.
