WebIn free fall (and to a lesser extent in a downward moving elevator), both you and the weighing scale are falling toward earth with the same acceleration. Therefore there is no … WebGravitational force F_g F g is always attractive, and it depends only on the masses involved and the distance between them. Every object in the universe attracts every other object with a force along a line joining them. The equation for Newton’s law of gravitation is: F_g = \dfrac {G m_1 m_2} {r^2} F g = r2Gm1m2.
Our weight on Earth depends on our mass, which is how much matter we are made of, as well as the force of attraction between our mass and the mass of planet Earth. This attractive … See more So what does this mean for orbiting astronauts? In space, astronauts and their spaceship still have mass and are still acted upon by Earth’s gravity.

As learned in an earlier unit, free fall is a special type of motion in which the only force acting upon an object is gravity. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity. Under such conditions, all objects ... solidity data typesWebFree-fall is the motion of objects that move under the sole influence of gravity; free-falling objects do not encounter air resistance.
