Greg and shawn are studying for a physical science test. greg thinks that the kinetic energy of an object depends on the height and speed of and object , but shawn thinks it depends on the bass of and object. who is right and why a. neither is completely right. shawn is partly correct since kinetic energy depends on mass , but greg is also partly right since it also depends on speed. b. both greg and shawn are correct since kinetic energy depends on mass, height and speed of an object. c. greg is right. increasing the height or speed of an object increases the kinetic energy of an object. d. shawn is right. the mass of an object determines the intertia of the object. increasing inertia is the only thing that will increase kinetic energy..

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
