The code below creates a ball and 10 smaller balls (for use as a “tail”, however the joint seams elasticated. I am sure that isn’t right, probably due to me pulling the “head” circle 
How can I stop it?
[lua]physics = require(“physics”)
physics.start()
physics.setGravity(0,0)
physics.setDrawMode( “hybrid” )
local Filter = { categoryBits = 2, maskBits = 3 } – collides with (2 & 1) only
local redBody = { density=0.2, friction=0, bounce=0.95, radius=43.0, filter=redCollisionFilter }
local blueBody = { density=0.2, friction=0, bounce=0.95, radius=43.0, filter=blueCollisionFilter }
local localGroup = display.newGroup()
local player = display.newCircle(400,200,50)
player:setFillColor(255,0,0)
physics.addBody(player, {radius = 50, filter=Filter})
localGroup:insert(player)
body = {}
bodyjoint = {}
body[1] = display.newCircle(player.x,player.y + 60,2)
localGroup:insert(body[1])
physics.addBody(body[1])
bodyjoint[1] = physics.newJoint( “distance”, player, body[1], player.x,player.y, body[1].x,body[1].y )
for i = 2,10 do
body[i] = display.newCircle(body[i-1].x,body[i-1].y+20,2)
localGroup:insert(body[i])
physics.addBody(body[i])
bodyjoint[i] = physics.newJoint( “distance”, body[i-1], body[i], body[i-1].x,body[i-1].y, body[i].x,body[i].y )
end
function move(event)
player.x = player.x + (event.x - player.x)/10
player.y = player.y + (event.y - player.y)/10
end
