You can use the Spring and Damper objects for dynamics effects.
Create panel > Space Warps on page 2685 > Particles and Dynamics.
Effects (forces) are special space-warp objects that emulate natural
phenomena, such as wind or gravity. In a dynamics simulation, you must
place gravity in the scene if you want the objects in your simulation to
fall.

Space Warps on page 2685 > Dynamics Interface.
The Dynamics Interface space warps can cause particles to deflect from
and affect an object in a simulation.
Combine Keyframed Objects in a Simulation: Keyframe an object and have it
interact with other objects in a dynamics simulation by turning on the This
Object is Unyielding check box in the Edit Object dialog for the keyframed
object. Objects can bounce off of a keyframed sphere for example.
Dynamics Controller: When a Dynamics simulation is solved, a new list
controller is created that holds both the generated dynamics keys and the
original keys. This allows you to restore your original keys, if necessary. Undo
is not supported by Dynamics.
For example, if a sphere is bouncing in a Dynamics simulation, and the sphere
already contains position keys from a previous animation, the following tracks
display in Track View:
Transform
Position
Dynamic Position Controller
Old Position
Rotation
Dynamic Rotation Controller
Old Rotation
Procedures
Example: To create a basic simulation of bouncing boxes:
1 Create a thin box in the Top viewport.
Have the box almost the same height and width as the viewport. This
will act as the ground plane.
2 In the Front viewport, create six small boxes above the "ground" box.
Position some of them to collide with each other when they fall.
