Question

An aeroplane flying at a height of 10,000 m, possesses _________ energy as well as ______ energy.

• A. potential
• B. kinetic

Answer 1

1. Kinetic energy is that energy that is possessed by the body when the body is in motion.

2. Mathematically, we can see that

Kinetic energy = $\frac{1}{2}\mathrm{x}\mathrm{mass}\mathrm{x}{\left(\mathrm{velocity}\right)}^2$

K.E = $\frac{1}{2}\mathrm{x}\mathrm{m}\mathrm{x}{\mathrm{v}}^2$

3. Potential energy attained by the body is defined as energy that will be due to its place with respect to the reference position.

4. Mathematically, we can see that

Potential energy (P.E) = mass (m) x acceleration due to gravity (g) x height (h)

P.E = m x g x h

5. Since the plane is flying at an altitude of 10000 m, it will definitely be moving with velocity whether variable or constant. So, the plane will possess kinetic energy due to its velocity and potential energy due to its height.

Hence, an aeroplane flying at a height of 10,000 m, possesses potential energy as well as kinetic energy.
