| [ApplyAngularImpulse](/engine/6000.6/script-reference/unity/u2d/physics/physicsbody/batchimpulse/applyangularimpulse.md)               | Apply an angular impulse. This should be used for one-shot impulses. If you need a steady torque, use a torque instead, which will work better with the sub-stepping solver. [PhysicsBody.ApplyAngularImpulse](/engine/6000.6/script-reference/unity/u2d/physics/physicsbody/applyangularimpulse.md).                                                                                                                                        |
| [ApplyLinearImpulse](/engine/6000.6/script-reference/unity/u2d/physics/physicsbody/batchimpulse/applylinearimpulse.md)                 | Apply an impulse at a point. This immediately modifies the velocity and also modifies the angular velocity if the point of application is not at the center of mass. This should be used for one-shot impulses. If you need a steady force, use a force instead, which will work better with the sub-stepping solver. [PhysicsBody.ApplyLinearImpulse](/engine/6000.6/script-reference/unity/u2d/physics/physicsbody/applylinearimpulse.md). |
| [ApplyLinearImpulseToCenter](/engine/6000.6/script-reference/unity/u2d/physics/physicsbody/batchimpulse/applylinearimpulsetocenter.md) | Apply an impulse to the center of mass. This immediately modifies the velocity. This should be used for one-shot impulses. If you need a steady force, use a force instead, which will work better with the sub-stepping solver. [PhysicsBody.ApplyLinearImpulseToCenter](/engine/6000.6/script-reference/unity/u2d/physics/physicsbody/applylinearimpulsetocenter.md).                                                                      |
