Samarpan Rai 30/11/012 Physics HL Investigation on Young Modulus Young’s modulus‚ also known as the tensile modulus‚ is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. Young’s modulus is named after Thomas Young‚ the 19th century British scientist. It is a very important concept that categorizes metals on basis of their elasticity. In the last lab‚ we were asked to find out the Young Modulus of two wires: Copper and Steel. I worked on Copper

LAB # 5 Relationship Between Drop Height and Diameter of Plasticine Sphere PROBLEM: A student suggest that there is a proportional relationship between height at which a plasticine sphere is dropped and the diameter of the flattened part after dropping. Design an experiment to determine if this suggestion is true or not. AIM: To investigate the relationship between the drop height and the flattened part of a plasticine sphere after being dropped. HYPOTHESIS: As the height of the sphere plasticine
