Question 11

Which of the following correctly describes Newton's first law of motion?

Accepted Answer

An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction, unless acted upon by an external force.

Answer

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

Answer

The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.

Answer

The force acting on an object is equal to the mass of the object multiplied by its acceleration.

Answer

The resistance of an object to a change in its motion depends on its mass.
