Hello, I’m trying to test just a simple setting using AddForce and I have difference between results from unity and results from math equation, Couldn’t find out what’s wrong any tips would be appreciated…

m = 1;

gravity and drag are turned off.

Starting position is (0; 0)

Objects final position becomes (202; 0). However with my calculations I should get (200; 0).

Since F=ma, (F = 100, m = 1) => a = 100.

S = 1/2 * a * t2 (t = 0.02 * 100, since deltatime for fixed update is 0.02 and I add force 100 times)

so I get S = 200, But unity says 202, I get similar results In case I use impulse force mode. What do I miss?

```
int count = 0;
float x = 100;
float y = 0;
Vector2 force;
Rigidbody2D rb2d;
void Start ()
{
rb2d = GetComponent<Rigidbody2D>();
force = new Vector2(x, y);
}
void FixedUpdate()
{
if (count < 100)
{
rb2d.AddForce(force);
}
else
{
rb2d.velocity = Vector2.zero;
rb2d.angularVelocity = 0;
}
count++;
}
```

If I set x = 10 final position is (2,2 ; 0). If I set x = 1, than - (0.04 ; 0). Neither of these match my calculations.
