Answer :
Final answer:
The transfer of kinetic energy is exemplified when a cat knocks a vase, transferring kinetic energy to it, and when a marble rolls and eventually stops due to friction, illustrating the conservation of energy principle in physics.
Explanation:
An example of the transfer of kinetic energy is when a cat knocks a vase over. In this situation, the cat applies a force to the vase causing it to move and potentially fall. This force transfers kinetic energy to the vase, which is initially at rest. As the vase moves and eventually falls, it is the cat's energy that is converted into kinetic energy of the vase. Another straightforward example is when a marble rolls into a corner. Here, the marble, which is in motion, possesses kinetic energy due to its velocity. As it rolls, this energy is transferred from the marble to the floor as friction does work on the marble, eventually bringing it to a stop.
These examples illustrate the conservation of energy, where kinetic energy is transferred from one system to another through the process of work. Essential Knowledge 4.C.2 from Physics tells us that mechanical energy is transferred into or out of a system when an external force is exerted on a system such that a component of the force is parallel to its displacement. This aligns with Big Idea 5 and Enduring Understanding 5.B that the energy of a system is conserved.
