When I am modelling a prismatic joint and I start the simulation the joint just drops under gravity and falls off. How do I limit the range of its motion

To do this, you can create a contact force that is applied to the joint based on some limits.

For a simple limit like this you can use the SimMechanics-Simscape interface blocks on the joint and connect it to a Translational Hard Stop block from the Simscape library.

For more complicated contact relationships, you may want to look at the SimMechanics Contact Library on the File Exchange.
