Which of the following best describes inertia?
Correct answer: B. The resistance of an object to a change in its state of motion
- A. The force of gravity acting on an object
- B. The resistance of an object to a change in its state of motion
- C. The weight of an object
- D. The acceleration of an object due to applied force
Explanation
Inertia is the property of an object to resist changes in its state of motion. According to Newton's First Law of Motion, 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. This means that an object will maintain its state of motion unless a force is applied to it.Inertia is a measure of an object's resistance to changes in its motion, and it is dependent on the object's mass. The more massive an object is, the more inertia it has, and the more force is required to change its state of motion.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
