Bowling machine

Ball velocity (Daan)

Measuring ball velocity

Using chronometer

Using bowling points system

Optimal ball velocity

16-17 mp/h = 27km/h

Increasing / decreasing speed (Daan)

Increasing height

Angle of swing

Using more/less force

Friction

Friction (Maarten & Robbe M.)

Friction coefficient

Measuring the coefficient of friction

changing angle method

Force of friction

Concepts

Pipe system (Michiel)

+ easy in use

- lack in velocity

non - electrical launcher (Kerem)

+ cheap, easy to move around

- does not fit requirements

Ballista (Robbe B.)

+ lot of speed boost

- hard to fabricate
