According to the third law of motion, if you exert a force on an object, the object exerts a force back on you that is:
- Less in magnitude and opposite in direction
- Greater in magnitude and same in direction

- Equal in magnitude and opposite in direction (correct)
Flashcards
Law of Inertia
Law of Inertia
An object remains at rest or in uniform motion unless acted upon by an external force.
Newton's Second Law
Newton's Second Law
The acceleration of an object is directly proportional to the net force acting on the object, is in the same direction as the net force, and is inversely proportional to the mass of the object.
Newton's Third Law
Newton's Third Law
For every action, there is an equal and opposite reaction.
Study Notes
Newton's Laws of Motion
- The first law of motion is also known as the Law of Inertia.
Second Law of Motion
- An example of the second law of motion is not specified in the given text, but it generally relates to the force and acceleration of an object.
Third Law of Motion
- If you exert a force on an object, the object exerts a force back on you that is equal in magnitude and opposite in direction.
