Analyzing the Relationship between Mass and KE
Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a
100 kg ball traveling at 5 m/s.
A 1,000 kg ball traveling at 5 m/s would have
v kinetic energy
A 10 kg ball traveling at 5 m/s would have
kinetic energy
A 100 kg person falling at 5 m/s would have
v kinetic energy

Which of your 24 wells had indications that a chemical reaction occurred? how were you able to tell that a chemical reaction occurred? which of your 24 wells had indications that a physical reaction occurred? how were you able to tell that a physical reaction occurred? report on both mixing and evaporation. make a general statement about whether your hypotheses were validated or rejected. must your hypotheses be correct for this to be a successful laboratory?
