Collision detection is not working for the player

Hi i'm new to unity, so really having a hard time to figure this out. i'm making an endless runner game and I have added a capsule collider and a rigid body component with no gravity to my player object. I have static objects in my scene with primitive colliders . My player is not colliding with the objects. I want my player to detect the objects, NOT pass through it. Can anyone help me out?
