public method AddForce(force: Vector2, mode: ForceMode2D = ForceMode2D.Force): void;
public void AddForce(Vector2 force, ForceMode2D mode = ForceMode2D.Force);

Parameters

force Components of the force in the X and Y axes.
mode The method used to apply the specified force.

Description

Apply a force to the rigidbody.

The force is specified as two separate components in the X and Y directions (there is no Z direction in 2D physics). The object will be accelerated by the force according to the law force = mass x acceleration - the larger the mass, the greater the force required to accelerate to a given speed.
