Question

what is an example of the transfer of kinetic energy? (1 point)
a marble rolls into a corner.
an air conditioner cools a room.
a student walks to school.
a cat knocks a vase over.

Explanation:

• Kinetic energy is the energy of motion. When a cat knocks a vase over, the moving cat (has kinetic energy) transfers its energy to the vase (causing it to move, i.e., gain kinetic energy).
• In "A marble rolls into a corner", there is no transfer of kinetic energy to another object.
• In "An air - conditioner cools a room", it is using electrical energy (not kinetic energy transfer in the sense of one moving object transferring energy to another).
• In "A student walks to school", it is the student's own body using chemical energy (from food) to move (kinetic energy of the student, no transfer to another object in the context of kinetic - energy - transfer as required).

Answer:

A cat knocks a vase over.
