Which statement about the gravitational force is true? There may be more than one; select all that are correct. OThe gravitational force between two objects increases as their masses increase The gravitational force between two objects is cut in half if the distance between them is doubled The gravitational pull of the Earth on the moon is bigger than the gravitational pull of the moon on the Earth because the moon is smaller than the Earth The sun has a...

Does the force of gravity
alone provide the means for the centripetal force, is this why they
are equal ? For explaining why there is no normal force, could you
see it as the astronaut having the same acceleration as the ship
and so the relative acceleration = 0, so it's under the illusion
almost of having no acceleration so there's no force ? Please !! If
you have different reasoning please share. I'm just trying to wrap
my head...

The following objects all have a net force of zero Newtons and are therefore in equilibrium. In each case some forces acting on the object are provided. Discuss the total number of forces acting on the object and add the missing forces. You may elect to choose from the provided list of forces, but feel free to discuss/provide a force that is not listed, if you feel your explanation is better. List of possible forces: Weight (The pull of gravity)...

Which of the following statements are IMPOSSIBLE? Choose all that apply. The parked motorcycle had 0 J of KE. The truck had 4019 J of KE and 524 kg∙m/s of momentum. A ball moving in a circle had 502 N of net force acting on it. A box had an acceleration of 0 m/s2 while a net force of 390 N acted on it. Jack exerted 96 N of force due west on a cart. As a direct result, the...
