Forces at a Distance

A student claims that the gravitational force between two objects depends upon the mass of the objects and the distance between them. Which argument best supports the student's claim?

• If the distance between two objects increases, the gravitational force between the objects will decrease.

• If the distance between two objects decreases, the gravitational force between the objects will disappear.

• If the distance between two objects increases, the gravitational force between the objects will increase.

• If the distance between two objects decreases, the gravitational force between the objects will not change.

Why doesn’t the gravitational pull between the Sun and the planets cause the planets to fall into the Sun?

• The background stars pull back on the planets.

• The Sun’s magnetic fields are pushing out.

• The speed of the planets flings them out.

• The Sun’s rotation pushes the planets out.

A student claims that the two magnets have a magnetic field that exists between them. What will occur that will support the student's claim?

• The magnets will repel each other as the closest poles have like charges.

• The magnets will repel each other as the closest poles have opposite charges.

• The magnets will be attracted to each other as the closest poles have like charges

• The magnets will be attracted to each other as the closest poles have opposite charges
