Questions & Step-by-Step Solutions
Which of the following correctly describes gravitational field lines?
Step 1: Understand what gravitational field lines are. They are imaginary lines that show the direction of the gravitational force around a mass.
Step 2: Know that each line represents the path a small mass would take if placed in the gravitational field.
Step 3: Realize that if two lines were to intersect, it would mean that at that point, there are two different gravitational forces acting on an object.
Step 4: Understand that this is not possible because an object can only experience one gravitational force at a time from a single mass.
Step 5: Conclude that therefore, gravitational field lines never intersect.
