Why an airplane flying from New York to Los Angeles has both kinetic energy and potential energy?
Kinetic energy: because it is moving.Potential energy: because it is above ground level. Note: This assumes that you measure potential energy from ground level; you can actually choose any altitude as your reference level.
Is a kite flying through the air kinetic energy?
If the feather is moving, it has kinetic energy. If there is room beneath the feather for it to fall, it has potential energy due to gravity.
How does the path of the crate appear to somebody on the airplane and to someone on the ground when a crate is dropped from an airplane flying horizontally at constant speed?
Person on the airplane: Crate will appear to be dropping straight down. Person on the ground: Crate will be curving in the direction the plane is moving.
An eagle flies from its perch in a tree to the ground describe the energy transformation?
Mechanical energy. It has both potential and kinetic energy.
What energy transformation occurs with a windmill?
Wind is produced by uneven heating of the ground. Heat:mechanical (kinetics)wind movement: turning: mechanical: engine systems :sounds.

Can aeroplane stay in the sky without movement?
Depends on what you compare it to. An airplane has to move in relation to the air to stay flying, but it doesn't really care about what the ground is doing. If it's windy enough you can point a slow-flying airplane into the wind and remain flying while not moving in relation to the ground.
How do you convert gravitational energy to mechanical energy?
when you stay on the ground the mechanical objects stay there too due to gravity.
Can a strong wind stop an airplane?
Yes, and any pilot can tell you about flying into a wind but moving backwards with respect to the ground. But be certain you understand that the airplane keeps flying, it just doesn't move forward.

What forms of energy are produced when a horse lands onto the ground with a thud?
sound energy from the 'thud' and mechanical energy to deform the ground (sound)

Person on the airplane: Crate will appear to be dropping straight down. Person on the ground: Crate will be curving in the direction the plane is moving.
Can an earthquake cause damage to an airplane flying at 30000 feet?
most likely no. the real damage is happening on the ground.

What does wheels up mean?
"wheels up" is when an airplane is off the ground. When someone says they are going "wheels up" it means they are flying soon.
What is the name of an airplane driving on the ground?
Moving an airplane on the ground is called 'taxiing'
