Can someone please, please help me with my Physics?

christopher Grzesik NEWTONS 2nd LAW LAB obj- to verify newtons 2nd law thru calculation and observation Procedure- observe and calculate ( pan 50 g , cart 500g, cart bars 500g) Data/calc. 2nd law part 1 MASS CONSTANT 1500g 1isks Hanging mass....... EF a 1) 250g. 2)500g. 3)1000g . OBSERVATION: when each slotidmasses was added the pan fell more quicker as they were drop in each triale 2nd law part 2. Constant Eforce (hanging mass 550g) .58ks Mass. A 1)500g. 2) 1000g. 3)2000g. OBSERVATION: when the bars was added to the cart the pan with loos shotid mass fell slower in each trial, Hint: hanging mass is not mass , hanging mass is used in weight equation , weight is used as net force , mass is used as m in EF=ma CONCLUSION
