Physics

The Physics Menu is an advanced feature, which gives you control on the physics and materials of individual objects. To access it, right click on an object and choose the Physics option.

Physics Menu

Rigidbody

Determines how the Object behaves when moving through space.

Setting Name What It Does
Use Gravity Enable being affected by gravity.
Mass Mass of the object. Uses arbitrary mass units
Drag How much air resistance affects the object when moving from forces. 0 means no air resistance, and infinity makes the object stop moving immediately. A low Drag value makes an object seem heavy. A high one makes it seem light. Typical values for Drag are between .001 (solid block of metal) and 10 (feather).
Angular Drag How much air resistance affects the object when rotating from torque. 0 means no air resistance. ou cannot make the object stop rotating just by setting its Angular Drag to infinity

Setting Gravity

Gravity is for the whole table and can be changed at the top of the screen under Options > Game.

Material

Determines how the Object behaves when impacting/touching other Objects.

Dynamic Friction vs Static Friction

Friction comes in two forms, dynamic and static. Static friction is used when the object is lying still. It will prevent the object from starting to move. If a large enough force is applied to the object it will start moving. At this point Dynamic Friction will come into play. Dynamic Friction will now attempt to slow down the object while in contact with another.

Setting Name What It Does
Static Friction The friction used when an object is laying still on a surface. Usually a value from 0 to 1. A value of zero feels like ice, a value of 1 will make it very hard to get the object moving.
Dynamic Friction The friction used when already moving. Usually a value from 0 to 1. A value of zero feels like ice, a value of 1 will make it come to rest very quickly unless a lot of force or gravity pushes the object.
Bounciness How bouncy is the surface? A value of 0 will not bounce. A value of 1 will bounce without any loss of energy.
