The Correct Answer and Explanation is:
✅ 10 Conceptual Facts: Newton’s First Law and Non-Acceleration
- Inertia resists changes in motion.
- An object at rest stays at rest unless acted upon by a net force.
- An object in motion continues in uniform motion unless acted upon.
- Acceleration requires a net external force.
- No net force means no change in velocity.
- Friction is a force that can stop or change motion.
- If all forces cancel out, the object is in equilibrium.
- Velocity (speed with direction) remains constant if no net force acts.
- Mass is a measure of an object’s inertia.
- Stationary or constant-speed motion is natural unless interrupted.
Explanation: Why Objects Don’t Accelerate – Newton’s First Law
Newton’s First Law of Motion, often called the Law of Inertia, states that an object will remain at rest or continue in uniform motion in a straight line unless acted upon by a net external force. This law highlights that acceleration only occurs when a net force is present.
The key concept here is inertia, which is an object’s natural resistance to changes in its state of motion. This means that a motionless object won’t start moving on its own, and a moving object won’t change its speed or direction unless something (a net force) acts on it. The tendency to maintain the current state of motion explains why objects don’t accelerate spontaneously.
When forces acting on an object are balanced (net force = 0), the object is in equilibrium. For instance, if a book rests on a table, gravity pulls it down while the table pushes it up with equal force—no net force, so no acceleration.
Even a moving object doesn’t accelerate if no force alters its velocity. A spacecraft in deep space, far from gravitational pull or friction, will continue at constant speed forever unless an external force (like a thruster) changes its motion.
Also, mass affects how strongly an object resists acceleration—heavier objects have more inertia.
Thus, Newton’s First Law explains that acceleration only arises from imbalance. When no such imbalance (net force) exists, objects simply keep doing what they were doing—either staying still or moving uniformly in a straight line.
