So i have found this one method to slow down a Rigidbody2D it required me to scale the velocities and mass by a factor (timescale) though this does not result in the same physics effect to happen (Without the timescale effected, a ball bounces a certain amount of times, though when the timescale has been lowered the ball bounces less).
What other ways are there to slow down a single Rigidbody2D?
