Which of the following best describes Newton's first law of motion?
Which of the following best describes Newton's first law of motion?
- The net force applied to an object is equal to the rate of change of its velocity.
- The rate of change of momentum of an object is directly proportional to the force applied.
- The force acting on an object is equal to the mass of the object multiplied by its acceleration.
- 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 unbalanced force. (correct)

Study Notes
Newton's First Law of Motion
- Newton's first law of motion states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity, unless acted upon by an external force.
Inertia and Mass
- Inertia is the tendency of an object to resist changes in its motion, and it is directly related to the mass of the object.
- The more massive an object, the more inertia it possesses, meaning it will be more difficult to change its state of motion.
Resistance to Change in Motion
- A body's resistance to a change in its state of motion is a result of its inertia, which is a fundamental property of an object.
Effect of Mass on Inertia
- A larger mass results in a greater amount of inertia, making it more challenging to alter the object's motion, and vice versa.
