More about the experiment

Hopefully by detailing the wording of the experiment, my experiment will be easier to understand.

'DOES TEMPERATURE AFFECT THE FORCE A RUBBER BAND CAN WITHSTAND BEFORE RUPTURE?'

Temperature is defined as the hotness or coldness of a body or environment. Temperature can be meausred using either Celcius, Fahrenheit of the Kelvin Scale. In my experiment, i'll be using (degrees) Celcius.

Elasticity is the tendancy of a material to return to its original shape after a load has been exerted on it. In my experiment however, i will be meausuring the load the rubber band can take before rupture by using a spring scale a.k.a. Newton Meter.

A spring scale measures the tension force applied to the object. Ultimately, a spring scale and a newton meter is the same thing; the spring scale meausures in kilograms (kg), whilst a newton meter measures in Newtons (N). If you multiply kilograms by 9.8m/s/s (metres squared and acceleration due to gravity) it will convert the amount of kilograms to Newtons.
