Physics help?! Forces!

[From: ] [author: ] [Date: 12-09-20] [Hit: ]
accelerating down the runaway: Force applied to make it accelerate and (-g) and (N=mg) -> (Fapp) and . air resistance (mostly ingnored) in x direction and .......
what forces act on a plane when it is stationary on a runaway, accelerating down the runaway, and climbing in the air?! I DO NOT GET FORCES! please help me??

thankyouuuuu x

-
stationary on a runaway: Force of gravity which is countered by the Normal Force . -> (-g) and (N=mg)
accelerating down the runaway: Force applied to make it accelerate and (-g) and (N=mg) -> (Fapp) and . air resistance (mostly ingnored) in x direction and . (-g) and (N=mg) in y direction
climbing in the air: (Fapp) in both x and y direction and (-g) and (N=mg) in y direction

-
Forces occuring when stationary: Gravity
Forces occuring when on a runway: Air resistance
Forces occuring in the air: Weight life thrust
The air resistance and thrust is going at a constant speed so this is called a BALANCED FORCE

-Hope this helped
