+    Summary:
+    Check that Set Gravity Enabled works on an entity with gravity that starts as disabled
+
+    Level Description:
+    Terrain (entity) - Terrain entity is created in the level
+    Sphere (entity) - Entity with PhysX rigid body, mesh and collider with gravity disabled placed above
+    the terrain
+
+    Expected Behavior:
+    After 5 seconds, when SetGravity is called, the entity falls to the ground
+    We are checking if entities are valid and enabling the gravity after 5 seconds in game mode to check if ball
+    falls on the terrain.
+
+    Test Steps:
+     1) Open level
+     2) Enter game mode
+     3) Retrieve and validate entities
+     4) Gravity check for entity
+     5) Enabling gravity after 5 seconds
+     6) Adding collision handlers for terrain
+     7) Checking if the object collides with terrain
+     8) Exit game mode
+     9) Close the editor
+
+
+    Note:
+    - This test file must be called from the Lumberyard Editor command terminal
+    - Any passed and failed tests are written to the Editor.log file.
+            Parsing the file or running a log_monitor are required to observe the test results.
