So the initial potential energy is equal to the final potential energy plus rotational kinetic energy, right?
Is the final translational kinetic energy also considered if energy is conserved?

Thank you very much!

Yes.Why not?
If it had potential energy initially and that energy is transformed to other types,then yes.
Please upload a valid picture.

FAQ: Conservation of Energy: No Translational KE?

What is conservation of energy?

The conservation of energy is a fundamental principle in physics that states that energy cannot be created or destroyed, but can only be transferred or transformed from one form to another.

What is meant by "no translational kinetic energy"?

Translational kinetic energy refers to the energy of an object due to its motion in a straight line. When we say "no translational kinetic energy," it means that the object is not moving and therefore has no energy associated with its motion.

Why is conservation of energy important?

Conservation of energy is important because it is one of the fundamental laws of nature that govern the behavior of the universe. It allows us to predict and understand the behavior of physical systems and plays a crucial role in many practical applications, such as in engineering and technology.

What are some examples of conservation of energy with no translational kinetic energy?

Some examples of conservation of energy with no translational kinetic energy include a stationary object on a shelf, a pendulum at the highest point of its swing, and a battery-powered clock when it is not ticking.

How is conservation of energy with no translational kinetic energy relevant to everyday life?

Conservation of energy with no translational kinetic energy is relevant to everyday life in many ways. For example, it explains why objects stay in place unless acted upon by an external force, why a pendulum eventually comes to a stop, and why batteries eventually run out of energy. It also plays a role in various forms of energy production and consumption, such as in power plants and transportation systems.
