The device detects an input on the touch-sensitive surface at a location that corresponds to a user interface object, including detecting a change in intensity of the input on the touch-sensitive surface from a first intensity to a second intensity. The device, in response to detecting the input, obtains a change in a value of a respective simulated physical parameter of a physics model that is driven by the change in intensity of the input on the touch-sensitive surface; and updates an appearance of the user interface by progressing an animation between a first state and a second state based on the change in the respective simulated physical parameter of the physics model.
