Yes for an object moving on a horizontal plane, R = mg (where mg = weight). therefore, for an object moving on a horizontal plane: F = μmg
GPE I am assuming is gravitational potential energy. I'll denote it as U for simplicity.
U = mgy
U = (70kg)(9.81m/s^2)(1m) = 686.7J
U = 686.7J
Hope this helps!
Answer:
newtons law of force
newtons law of force explains that something may or can or canot move depending on the objexts mass.
Answer: Its applied force and friction, The friction is the drag and the applied force is you pushing
