# Physics

By default, objects are anchored in place. If we set this property to false, objects come to life!

## Functions

### object.push(x, y)

Give an object a push in the direction defined by x and y. This is the same as momentarily increasing the acceleration. If the object is anchored, it will become unanchored.

## Properties

### object.bounciness

A `Number`

between 0 and 1 defining how "bouncy" an
object is.

### object.velocity.x

A `Number`

defining the object's velocity, or speed, along
the x-axis.

### object.velocity.y

A `Number`

defining the object's velocity, or speed, along
the y-axis.

### object.x

A `Number`

defining the object's x coordinate.

### object.y

A `Number`

defining the object's y coordinate.

## Events

### collision

The collision event fired when two objects smash into each other.
