Answer:
The two forms of energy that increase during the time after take off are;
1) The kinetic energy KE
1) The potential energy PE
Explanation:
1) Given that the airplane is accelerating, we have that the velocity, v, of the airplane is increasing, such that the we have the kinetic energy, KE, for a given mass, m, of the airplane increasing as follows;
KE₂ = 1/2×m×v₂² > KE₁ = 1/2×m×v₁²
2) Also, as the height, h, of the airplane increases during the ascent, we have that the potential energy increasing along side as follows;
PE₂ = m × g × h₂ > PE₁ = m × g × h₁
Therefore, the two forms of energy that increase during the time after take off are the kinetic and the potential energy.
