Asked by Makayla
What is true of the aircraft in the picture? Select all that apply.
The mechanical energy of the plane = kinetic energy of the plane + potential energy of the plane.
It does not have any kinetic energy because gravity is pulling on it giving it potential energy.
It does not have any potential energy because it is moving.
It has kinetic energy because it is moving.
It has potential energy because it is above the earth.

Correct choices:
- The mechanical energy of the plane = kinetic energy of the plane + potential energy of the plane.
- It has kinetic energy because it is moving.
- It has potential energy because it is above the earth.
Why: kinetic energy = 1/2 mv^2 if the plane is moving, and gravitational potential energy = mgh relative to the ground if it is above the Earth, so the plane has both. The other two statements are false: motion does not eliminate potential energy, and gravity “pulling” does not mean the object has no kinetic energy or that potential energy is somehow replaced by gravity.
