Question

1. newtons 3rd law states

an object at rest remains at rest and an object in motion remains in motion at a constant velocity unless acted upon by an unbalanced force
when one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the objects mass
none of the above

Explanation:

• Newton's 1st Law: An object at rest remains at rest and an object in motion remains in motion at a constant velocity unless acted upon by an unbalanced force.
• Newton's 2nd Law: The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object's mass ($F = ma$).
• Newton's 3rd Law: When one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.

Answer:

When one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.
