• Pinball with matter.js

Install requirements

npm install

Building with gulp

gulp build
gulp watch

Physics

Planck.js was chosen in favour of matter.js, because of the tunneling happening during the collision between flipper & ball with the latter.

Torque

Twisting force that causes the rotation (rotational equivalent of linear force).

$ \tau = f \cdot r \cdot sin \theta $

where:

• \tau: torque.
• f: force.
• r: lever.
• \theta: angle between the force and the lever.

Speed and acceleration

$ v = v_0 + a \cdot t $

with:

• v: speed.
• v_0: initial speed.
• a: accelration.
• t: time.

Force

$ f = m \cdot a $

where:

• f: force.
• m: mass (in kg), a measure of inertia that affects how quick speed can change (i.e. acceleration).
• a: acceleration (e.g. gravity).

Power

$ p = \tau \cdot \omega $

where:

• p: power.
• \tau: torque.
• \omega: angular speed.
