How does the rigidbody function work in Unity?

Adding a Rigidbody component to an object will put its motion under the control of Unity’s physics engine. Even without adding any code, a Rigidbody object will be pulled downward by gravity and will react to collisions with incoming objects if the right Collider component is also present. The Rigidbody also has a scripting API

How does a rigidbody add force to an object?

Adds a force to the Rigidbody. Applies force at position. As a result this will apply a torque and force on the object. Adds a force to the rigidbody relative to its coordinate system. Adds a torque to the rigidbody relative to its coordinate system.

Which is an example of a rigidbody API?

The Rigidbody also has a scripting API that lets you apply forces to the object and control it in a physically realistic way. For example, a car’s behaviour can be specified in terms of the forces applied by the wheels.
