the law of conservation of energy states that energy cannot be created or destroyed it can only be transformed. now infer how all of the energy you have comes form the sun?

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
