Give an example of an object that has balanced forces acting on it.

If the forces on an object are balanced (or if there are no forces acting on it), this is what happens:

a stationary object stays still
a moving object continues to move at the same speed and in the same direction

When two forces are the same strength but acting opposite direction they are called balanced forces again tug-of-war is a perfect example if the people on each side of the rope are pulling with the same strength but it opposite direction the forces are balanced the result is no motion

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
