# Class: ContactImpulse Contact impulses for reporting. Impulses are used instead of forces because sub-step forces may approach infinity for rigid body collisions. These match up one-to-one with the contact points in Manifold. ## Constructors ### new ContactImpulse() > **new ContactImpulse**(`contact`): [`ContactImpulse`](/api/classes/ContactImpulse) #### Parameters • **contact**: [`Contact`](/api/classes/Contact) #### Returns [`ContactImpulse`](/api/classes/ContactImpulse) ## Accessors ### normalImpulses #### Get Signature > **get** **normalImpulses**(): `number`[] ##### Returns `number`[] *** ### tangentImpulses #### Get Signature > **get** **tangentImpulses**(): `number`[] ##### Returns `number`[] ## Methods ### recycle() > **recycle**(): `void` #### Returns `void`
