Margarine Carton Investigation

Aim:

To investigate what affects how far a margarine carton can be catapulted.

Infomation:

Below are the different factors that can be varied to affect the distance that margarine travels when fired from an elastic band.

Weight Of The Carton-

Depending on the weight of the carton the distance it travels will vary.  If the carton is heavy it will travel less than if it was lighter.

Surface-

No matter how smooth a surface is, it will always have imperfections.  Depending on the surface the carton will be travelling on there will be different amounts of friction.

Length Elastic Band Is Stretched-

Energy can be stored in elastic materials.  When an elastic band is stretched it stores potential energy.  Depending on how much the band is stretched it will vary the distance the carton travels.

Shape Of Carton-

If a carton is more streamline it has less air resistance and is not slowed down as much as a carton that has lots of air resistance.

Hypothesis:

During my investigation I am going to change the length the elastic band is stretched back and the weight of the carton.  I predict the further back the elastic band is stored the bigger the distance the carton will travel once fired.  In my second experiment I predict if I increase the weight of the carton it will lose distance.

Apparatus:

During my experiment ...
