Question

When a pendulum is held high and taut and then is released, the pendulum begins to swing. What’s the correct order of the energy transformations in this example? (PE stands for potential energy.) A. gravitational PE → elastic PE → thermal energy B. gravitational PE → kinetic energy → thermal energy C. kinetic energy → elastic PE → thermal energy D. kinetic energy → gravitational PE → thermal energy E. thermal energy → gravitational PE → kinetic energy

Answer 1

Answering: I believe it’s A

Explanation:

Answer 2

The correct option is (B) gravitational PE → kinetic energy → thermal energy.

Given:

A pendulum is held high and taut and then it is released, the pendulum begins to swing.

Explanation:

• So, let's say this has gravitational potential energy, and let's imagine the bottom most point is that temple. If we keep it over here for this long is that the gravitational potential energy will be stored.

• When we release it, it will begin to fall. As a result, the height difference between the data and the beginning position or pendulum position will decrease. As a result, gravitational potential energy will decrease, and kinetic energy will take its place.
• After this moment, kinetic energy will begin to decrease and gravitational potential energy will begin to increase again, almost to the point where we are now. Technology would be non-existent, and gravitational potential would be at its peak.
• Now gravitational potential energy will be converted to kinetic energy, which will be lost in the form of hit energy slowly but steadily. Or, we can say, thermal energy, because do you believe there would be some resistance in that location, and because of the resistance of air, heat would be generated so slowly that this older energy will be lost in the form of heat.

Thus, gravitational potential energy becomes kinetic energy, which is represented by these two thermal energies.
