Marcus is teaching a lesson on energy transformations to his class. He cracks a glow stick to teach this practice and states that the energy in the glow stick is transformed. Assuming that the glowstick is a closed system and all of the energy gets transfomred, explain how the chemical energy of the glow stick compares to the light energy after he cracks it.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
