Which quanity is the transfer of energy? a) motion b) force c) work

Answer: work

Explanation:

Force is not a quantity of the transfer of energy. An example of force would be when you push on a wall. You are applying force on a wall but the wall doesn't move. Thus, there is no transfer of energy.

The SI unit for force is Newtons (N)

Motion is a representation of force, not a quantity of the transfer of energy. When you see a ball rolling on the ground, this is because something pushed it and applied force, or the force of gravity is pulling down on it. There is also no transfer of energy in motion.

The SI unit for motion is Meters Per Second (m/s)

Work is the quantity of the transfer of energy. If you were to push on a door and it opens, energy has been transferred from your arms to the door; thus, there is work present.

The SI unit for work is a Watt (W), or Joules per Second (j/s)

c) work

Explanation:

Energy is the ability to do work and work changes the energy of objects. Work requires the application of force over a distance to achieve that change in energy ... Work equals the force times the distance, in units of Newtons times Meters
