A flying aeroplane possessesa)only potential energyb)only kinetic energyc)both potential and kinetic energyd)neither potential nor kinetic energyCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

An aeroplane while flying will have both Potential and Kinetic Energy because,
While flying it will be at a height. let's say 'h'.
Due to gravitational force it possesses Gravitational Potential Energy=mgh.
(where 'm' is the mass of aeroplane, 'g' is the gravitational acceleration and 'h' is the height above the ground where it flies).
While flying it moves (or) it is in motion.
So,it possesses Kinetic energy=1/2mv^2.
(where 'm' is the mass of aeroplane and v is the velocity at which it is moving).

Answer

Correct answer is option c because it is flying above ground level it will posses potential energy and since it is moving with the motion associated through it, it possesses kinetic energy.

Answer

A flying aeroplane has potential energy has it flies above the ground level. And since the aeroplane is flying motion is associated with it and thus possesses kinetic energy. Hence a flying aeroplane has both potential and kinetic energy.

Answer

Potential Energy:
Potential energy is the energy possessed by an object due to its position or condition. It is the energy that can be transformed into other forms of energy. In the case of a flying airplane, it possesses potential energy in the form of gravitational potential energy. When the airplane is at a certain height above the ground, it has the potential to fall and do work on the ground due to the force of gravity. This potential energy can be calculated using the formula PE = mgh, where m is the mass of the airplane, g is the acceleration due to gravity, and h is the height of the airplane above the ground.

Kinetic Energy:
Kinetic energy is the energy possessed by an object due to its motion. It is the energy that an object possesses because of its speed and mass. In the case of a flying airplane, it possesses kinetic energy due to its motion through the air. The airplane is constantly moving, and this motion gives it kinetic energy. Kinetic energy can be calculated using the formula KE = 1/2mv^2, where m is the mass of the airplane and v is its velocity.

Explanation of Option C:
The correct answer is option C, which states that a flying airplane possesses both potential and kinetic energy. This is because an airplane in flight is in motion, so it has kinetic energy. At the same time, it is at a certain height above the ground, so it also has potential energy. Therefore, an airplane possesses both types of energy simultaneously.

Example:
To understand this concept better, let's consider an example. Imagine an airplane flying at a certain altitude above the ground. The airplane has a certain mass and is moving at a specific velocity. At this moment, the airplane has both potential and kinetic energy. The potential energy is due to its height above the ground, and the kinetic energy is due to its motion through the air.

Conversion of Energy:
During its flight, the airplane can convert its potential energy into kinetic energy and vice versa. For example, if the airplane starts descending, it loses potential energy as it gets closer to the ground. At the same time, its velocity increases, leading to an increase in kinetic energy. On the other hand, if the airplane begins to climb, it gains potential energy as it moves higher above the ground. At the same time, its velocity decreases, resulting in a decrease in kinetic energy.

Conclusion:
In conclusion, a flying airplane possesses both potential and kinetic energy. The potential energy is due to its height above the ground, while the kinetic energy is due to its motion through the air. These two forms of energy can be converted back and forth as the airplane changes its altitude and velocity.
