PHYSICS UNIT 2 Physics P2 for GCSE Additional Science or GCSE Physics AQA GCSE Science PHYSICS 2 Unit P2.1 Forces and their effects Appreciate that forces can cause changes to the shape or motion of an object. Not only can objects can move in a straight line at a constant speed but they can also change their speed and/ or direction (accelerate or decelerate). Be able to use/produce graphs can help us to describe the movement of an object. These may be distance-time graphs or velocity-time graphs

Physics (from Greek φυσική (ἐπιστήμη)‚ i.e. "knowledge of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is the natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

Conclusions: We learned that some nasty stains can come out with some unorthodox products. We used on our stain Isopropyl alcohol (rubbing alcohol)‚ bleach‚ and shout. The product that did the best at pulling out stains was the Isopropyl alcohol. Isopropyl alcohol is a clear‚ colorless‚ flammable‚ mobile liquid‚ (CH3)2CHOH‚ used in antifreeze compounds‚ in lotions and cosmetics‚ and as a solvent for gums‚ shellac‚ and essential oils. It did great job at pulling stains right out of the cloth. This

General Conclusion: These experiments helped us understand the importance of molecular polarity. This knowledge can now be used for the future to predict‚ for example‚ if two substances will mix or not. We can now do this by knowing that polar substances only mix with other polar substances‚ while non-polar substances only mix with other non-polar substances. This concept can be used to predict if a substance will be soluble in a specific solvent. The concepts of solubility and conductivity of a
