    What is the nature of the unbalanced gravitational forces acting on these?

    A simple pendulum.

    Earth moving around the sun.

    Clothes rotating in a spin dryer.

    A car travelling round a bend.

    Electron moving around the nucleus in an atom.


    So far I've answered 1 and 2, as tensional force and gravitational force.

    But I'm unsure about the rest?

    I am not sure about 3 but i think it is gravitational potential. I don't know 4 and i think 5 is electrostatic attraction.

    3rd is circular motion because of the machines motors and 4th is centripetal?

    Ohhh nvm I see. I think you misinterpreted the question. Its not asking what the force against gravity is, but what type of force the gravitation force is. For instance, in the first one gravity acts as a restoring force and in the second one it acts as a rotational force. Can you do the rest now?
