Force and Motion

Choose the BEST answer that describes how the mass of an object affects its motion.

• The greater the mass of an object, the slower the motion of the object.

• The greater the mass of an object, the faster the motion of the object.

• The greater the mass of an object, the greater the force to move the object.

• The greater the mass of an object, the greater the distance the object will travel.
