Rigidbody2D.AddForce

Parameters

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.
