DOK Level 1: Recall

Formulate a hypothesis about the relationship between the mass of an object and the force needed to move it.

• The greater the mass, the less force is needed to move it.

• The greater the mass, the more force is needed to move it.

• The mass does not affect the force needed to move it.

• The mass and force are inversely related.
