Models that are to scale are most useful for showing
the relationships between the sizes of things and the distances between them.
the number of items in the solar system
the order of the planets
what color each planet is
Why is it diffiicult to make a model the solar system with both the sizes and the distances being accurate and to scale?
Because we do not know what is in the solar system
Because the sun is so large and the distances so great
Because of the immense distances and the fact that things are so small in comparison
Because we do not know the actual distances
What force does the string represent? What would happen if the string was suddenly let go? What force does this represent?
The string represents the pull of gravity between the hand and the ball. If released the ball would be pulled into the center.
The string represents the push of gravity. Nothing would happen to the the ball, it would just continue in its orbit due to the pull of inertia.
The string represents the pull of inertia. If released the ball at the end would fly off due to the pull of gravity.
The string represents pull gravity. If released the ball at the end would fly off due to inertia.
