Rotate projectile towards forward vector?

I want a projectile (that bounces) to rotate towards the direction it is traveling and then when bouncing it rotates towards its new direction. Essentially the projectile is ‘tumbling’ in the direction it is going. Simulate rolling physics direction without the physics.
