How to differentiate landing on top of an object from falling down the side?
There are three common ways games sort this out:
Minimum Separation Vector
Upon a collision, compute the shortest movement that pushes the bodies apart into a non-intersecting position.
If I've ...

How to control jump strength by how long the player presses the jump button?
You have essentially 2 options. You can either apply a constantly decreasing force to the character while the player is pressing the space button and stop immediately when they release it or apply a ...

Logical math behind jumping in a 3D world
It's the same as you'd do it for 2D, just with an extra axis. Use the same exact equations you do for a 2D game, something similar to the equations of motion or the kinematics equations.

Prevent player from jumping on a mesh
You could modify the existing collider on the mesh so that it is less "realistic" (aka less form-fitting) but better blocks the area in question.
You could also just remove the collider altogether ...

Creating proper jump mechanics in LibGDX with Box2D?
SMB "weakens" gravity to extend jump height when these three conditions are met:
You are still moving upwards.
You didn't release the jump button since you left the ground.
You didn't collect a power ...

Keep platformer jump height consistent with different frame rates
You need to decouple the render frequency from the simulation frequency: You measure the delayed time, do an appropriate amount of simulation steps, then render the frame.
