What equation correctly represents Newton's second law of motion?

• Net force x acceleration=mass

• velocity=distance/time

• acceleration=net force/mass

• False

The greater the force that is applied to an object of a certain mass, the more the object will ________.

• The object moves in the opposite direction.
• The object remains at rest.
• The greater the acceleration of the object.
• The smaller the acceleration of the object.

What does Newton's third law of motion state?

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

• Force equals mass times acceleration.

• Every object in a state of uniform motion will remain in that state unless an external force acts on it.

• Gravity is directly proportional to mass and inversely proportional to the square of the distance between two objects.
