Rigidbody physics

In physics simulation, rigid bodies enable physics-based behaviour such as movement, gravity, and collisionA collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a Rigidbody component and is in motion. More info

.

In Unity, you can configure rigid bodies with the Rigidbody class, or the corresponding RigidbodyA component that allows a GameObject to be affected by simulated gravity and other forces. More info

component.

Topic Description
Introduction to Rigidbody physics Overview of the concepts and fundamental behaviours of the Rigidbody class and component.
Configure Rigidbody colliders How to configure CollidersAn invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh - a rough approximation is often more efficient and indistinguishable in gameplay. More info

on a Rigidbody so that the physics system can accurately detect collisions.
Apply constant force to a Rigidbody How and when to apply a constant linear or rotational force to a Rigidbody GameObjectThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info

Apply interpolation to a Rigidbody How to use interpolation to smoothen the movement of a Rigidbody if it appears jittery at runtime.
