Question

Теорема о кинетической энергий плиз нужно для экзаменов тот кто ответит попадёт в рай

Answer 1

Словами теорема звучит так: Изменение кинетической энергии тела (или системы тел) равно работе всех внутренних и внешних сил, действующих на тела системы.

A=mVкон²/2-mVнач²/2

В задачах так чаще всего рассчитывается работа силы трения.

Answer 2

Theorem of Kinetic Energy

The theorem of kinetic energy, also known as the work-energy theorem, is a fundamental principle in physics that relates the work done on an object to the change in its kinetic energy. This theorem is crucial in understanding the relationship between work, energy, and the motion of objects.

Key Points: - The theorem of kinetic energy states that the work done on an object is equal to the change in its kinetic energy. - It provides a valuable tool for analyzing the motion of objects and understanding the transfer of energy.

The theorem can be mathematically expressed as:

W = ΔKE

Where: - W represents the work done on the object - ΔKE represents the change in kinetic energy of the object

This theorem is widely used in various fields of physics and engineering to analyze and predict the behavior of systems involving the transfer and transformation of energy.
