Can anyone write it for me ?

 

It's a fairly simple script, I recommend you dig into the Learn section so you understand what the code in your game is actually doing.

To get you started, in your Update() method you can call Input.GetKeyDown() to check if a player presses space. If true, toggle a boolean that determines whether the object should be accelerating or not.

Code (csharp):

1. private bool shouldAccelerate = false;
2.  
3. void Update()
4. {
5.      if(Input.GetKeyDown(KeyCode.Space))
6.      {
7.           shouldAccelerate = !shouldAccelerate;
8.      }
9.      if(shouldAccelerate)
10.      {
11.           // do your acceleration here
12.      }
13. }
