Remarks

Damping can be used to reduce the magnitude of the _linearVelocity (linear speed) of a Rigidbody2D over time.
Zero indicates that no damping should be used whereas higher values increase the damping, effectively slowing down the linear motion faster. Unlike contact friction, linear damping is always applied.
Note: The following formula is how the linear damping is applied: 
linearVelocity "= 1.0f / ( 1.0f + simulation-time-step " linearDamping )

Examples

using UnityEngine;public class ExampleClass : MonoBehaviour{    private Rigidbody2D rb;    void Start()    {        rb = GetComponent<Rigidbody2D>();    }    void Update()    {        if (Input.GetButton("Fire1"))            OpenParachute();        if (Input.GetButton("space"))            CloseParachute();    }    void OpenParachute()    {        // Set a large damping to simulate an open parachute.        rb.linearDamping = 20f;    }    void CloseParachute()    {        // Turn-off damping to simulate a closed parachute.        rb.linearDamping = 0f;    }}
