Adding Force to a rolling ball

I have a game im building for a class project that is a ball track. The ball rolles down the track from an angle and should roll to the end. The problem is I can not get enough momentum from my hill for it to make it to the end.

What im needing is a way to add force to the ball when it rolls though an invisible collider on the track. I want it to add the force in the same direction its going.

I’m not sure if i understood it, first of all I would add a rigidbody to the ball, once it has one add the following code:

rigidbody.AddForce(0, -forceValue,0);

This will add negative force to your ball on the y axis(relative to world space).
So it the ball is actually rolling “down”…it will move faster.

Hope it helps.
