• An object at rest remains at rest.

• Friction opposes the motion of an object.

• For every action, there is an equal and opposite reaction.

• The net force is directly proportional to mass and inversely proportional to acceleration.

• They will both accelerate at the same rate.

• None of them will accelerate greater than the other.

• The one with a mass of 0.3 kg has the greater acceleration.

• The one with a mass of 0.4 kg has the greater acceleration.
