If the distance between two objects is doubled, how does the gravitational force between them change?

• The gravitational force remains the same.

• The gravitational force decreases by a factor of 2 (2x smaller)

• The gravitational force decreases by a factor of 4 (4x smaller)

• The gravitational force increases by a factor of 2 (2x bigger)

In the context of the inverse square law, why does the intensity of a force decrease as the distance increases?

• Due to the force becoming stronger with distance

• As a result of the force being refracted by distance

• Due to the spreading out of the force over a larger area.

• Because the force is more concentrated at a distance

Discuss the significance of the inverse square law in understanding the behavior of gravitational and electric forces.

• The inverse square law explains how gravitational and electric forces diminish with distance.

• The inverse square law is irrelevant in understanding how forces behave

• The inverse square law states that forces become stronger with distance between objects

• The inverse square law only applies to magnetic forces
