فقدان الطاقة في مقاومة الهواء: كيف ، أي نوع ، كيف تحسب


Every object traveling in the air possesses حركي و محتمل energies, but a part of its energy is lost in the air. Let us discuss how and what energy is lost in air resistance.

The energy loss in مقاومة الهواء is the total dissipated energy due to تآكل and friction of air molecules while the body penetrates through the air volume. The air resistance force is always exerted in the opposite direction to the object’s velocity, causing friction and leading to mechanical energy loss.

We shall study precisely and learn how air resistance force can affect the energy possessed by an object and what different types of energy are lost due to air resistance. In this topic, we shall further find out how to calculate the total energy lost in air resistance.

How does air resistance affect energy?

Air resistance affects the طاقة الجاذبية الكامنة of an object during its free fall. Let us try to understand how air resistance can affect the energy of an object.

Air resistance affects energy by dissipating a part of energy in the air friction and heat. The energy loss is due to the rubbing of air molecules in the air on a body moving through the air column that causes friction. The قوة الإحتكاك often generates heat, thus, reducing the energy of an object moving in the air.

What type of energy is lost due to air resistance?

The total energy of an object is reduced due to air resistance. Let us ponder on different types of energies lost in this process by an object.

The object penetrating through the air volume loses its kinetic, gravitational potential, and mechanical energy due to air resistance. The molecular air friction lowers these energies, and the gravitational potential energy is lost due to the effect of خطورة as the height of an object constantly decreases while returning down the ground.

How to calculate energy loss in air resistance?

There are a few methods to calculate the total energy loss of an object due to air resistance. Let us learn how to calculate the same here below.

The energy loss in air resistance is found by measuring the total energy dissipated by the air resistance. The total energy loss is equal to the product of the air resistance force and the displacement of an object in the air. It is also inevitable for the variation in the gravitational potential energy of an object.

The formula to calculate the energy loss is E = W = Fd, where E is the energy lost, W is the work done by air resistance, F is the air resistance force, and d is a displacement. It is also equal to ∆U, which is a change in gravitational potential energy.

في الختام

We can conclude with this article that the energy loss in air resistance is due to the abrasion and friction of air molecules in the object’s surface while it makes a drift through the air column. Air resistance is inevitable for the loss of kinetic energy, gravitational potential energy, and the total mechanical energy of an object.
