Bowling machine

Concepts

Ballista (Robbe B.)

- hard to fabricate

+ lot of speed boost

non - electrical launcher (Kerem)

- does not fit requirements

+ cheap, easy to move around

Pipe system (Michiel)

- lack in velocity

+ easy in use

Friction (Maarten & Robbe M.)

Force of friction

Measuring the coefficient of friction

changing angle method

Friction coefficient

Increasing / decreasing speed (Daan)

Friction

Using more/less force

Angle of swing

Increasing height

Ball velocity (Daan)

Optimal ball velocity

16-17 mp/h = 27km/h

Measuring ball velocity

Using bowling points system

Using chronometer
