If you decrease or increase the mass of an object, does the force exerted by Earth (force of gravity) change as well?

    Also, for example, say we have accelerating fan cart on a track, if we add more mass to the cart, does the force exerted by the track change? What about the force exerted by the wind (from the fan)?

    I said for the original question: Because the cart now has more mass, the Earth exerts a greater force on it.

    Yes, if there's more mass, the gravitation force will be more. For the cart question, I don't know if those particular forces change. I think overall the force isn't constant and you have to consider the change in momentum

    Alright, thank you. Would it help if you had this information? "The fan cart (mass 0.683 kg) was once again accelerated down the track by moving air, which exerted a force of 0.34 N on the cart. This time, however, an unknown mass was added to the cart. [...]"
