    Astronauts who spend long periods in outer space could be adversely affected by weightlessness. One way to simulate gravity is to shape the spaceship like a cylindrical shell that rotates, with the astronauts walking on the inside surface. Explain how this simulates gravity. Consider

    (a) how objects fall,

    (b) the force we feel on our feet,

    (c) and other aspects of gravity you can think of

    The force of gravity is the force experienced by all objects on the surface of earth due to earth's gravitational pull. This force is also known as weight of the object and is equal to mg where m is the mass of the object and g is the acceleration due to gravity (9.8 m/s^2). An object falls to the ground due to this force only. When a person stands on the ground, he/she pushes the ground below with a force equal to his/her weight and the ground pushes back (upwards) his/her feet with equal force.
