The ground
You can define a frame of reference depending on your point of view, but it would normally be the Earth.
Either of these is referred to as positive acceleration: A) the object's velocity is increasing in the frame of reference B) the object is being moved in a positive direction in a coordinate plane
An inclined plane is an example of a tool with no moving parts. This is because it is used to assist.
When you want to compare something or measure something, in order to make the comparison you have to know and agree where you are starting from. The point at which you are starting is your "reference point"
The ground
the clouds
If the frame of reference is the ground, and if you are running forward, you are indeed moving faster than the plane. If you are running toward the rear of the plane, you are moving slower than the plane.

it will have the same ground speed (or very similar), but its indicated air speed, (speed in relation to air molecules around it) will be slower. Unless it is a very fast bee flying in circles within the car... The key to the answer is the frame of reference. To the pilot, his stationary frame of reference is the surface of the earth. Relative to that frame, he is moving at a high speed. The frame of reference for the bee or an observer of the bee in the plane is the interior of the plane. So choose your frame of reference before you think through the problem. The pilot is actually on a planet moving through in orbit around the sun at about 19 miles per second, but because he cannot perceive that motion, it is ignored and he tries to get the best groundspeed (across the surface of the earth) given the prevailing winds at various altitudes (his frame of reference....the surface of the earth). == ==
That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.That should be the same; what matters to the plane is the velocity in relation to the air, not in relation to some frame of reference outside the Earth.
Zero. I am currently sitting in my chair in my room. If the plane is my chair and my room is the reference plane as long as I don't move my chair around the room it has no kinetic energy. Now if I expand my reference plane to an observer on the sun (I know) they are going to see me and my chair hauling butt at about 30km/s around the solar system along with my room my house and the rest of the planet this velocity and my mass mean there is kinetic energy. Ek=.5mv^2
From one viewpoint just a matter of frame of reference...
It has no depth (z) value, only x and y, it is two dimensional only, used for calculation purposes mostly
roller coaster is a moving inclined plane
The speed of light is constant in its reference plane. You could never observe light moving more slowly, except when it refracts through a transparent medium.
