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 an object, but shawn thinks it depends on the mass of an object. who is right and why? greg is right. increasing the height or speed of an object increases the kinetic energy of an object. 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. both greg and shawn are correct since kinetic energy depends on mass, height and speed of an object. shawn is right. the mass of an object determines the inertia of the object. increasing inertia is the only thing that will increase kinetic energy..
