Does AddForce in rigidbody2D work in m/s?


I am a bit confused about physic units in unity.

I have read that unity default distance unit is in meters and speed is in m/s. I have a little test map made of 1x1x1 cubes and when I launch a projectile say at a velocity of (0,20) it doesn’t travel at 20cubes/s. It travels much slower. Am I missing something?

Thanks in advance.

Force and velocity are two different things. If you add force, you are adding 20 newtons (depending on the mass of your object). And, it depends on how you are applying. Are you applying once, are you applying every update? What is the force mode; impulse, force?
But yes,

velocity is in m/s, 

acceleration is m/s^2 


force is newtons, 1kg(m/s^2).
