Gravity problem in Jbullet

[harrysjoerd]

I use the Jbullet physics engine, but I have some problems with it. As the parameter for stepSimulation I use 1/60. Gravity I have set on -9.81. The mass of my ball is 10. Now when I drop the ball with radius 10 from height: 40. The camera, which is 150 away, shows the dropping ball, but it takes 6 seconds before the ball hits the ground. I seems that it is shown in slow motion. Setting gravity to -100 resolves this, but of course I want to solve it correctly. Can anyone help me with this?

You could try increasing the mass of the ball.
