FAQs on Newton's First law of motion Video Lecture - Physics

1. What is Newton's First law of motion?
Ans. Newton's First law of motion, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will continue moving with the same velocity unless acted upon by an external force.
2. How does Newton's First law of motion explain inertia?
Ans. Newton's First law of motion explains inertia, which is the tendency of an object to resist changes in its motion. According to this law, an object at rest will remain at rest because it lacks the external force required to overcome its inertia and set it in motion. Similarly, an object in motion will continue moving at a constant speed and direction unless an external force acts upon it to change its motion.
3. Can you provide an example that demonstrates Newton's First law of motion?
Ans. Yes, an example that demonstrates Newton's First law of motion is when a passenger in a moving car suddenly applies the brakes. The passenger tends to lunge forward because their body has the tendency to remain in motion due to inertia. The seatbelt provides the external force that prevents the passenger from continuing to move forward.
4. How is Newton's First law of motion relevant to everyday life?
Ans. Newton's First law of motion is relevant to everyday life in various ways. For example, it explains why objects tend to stay at rest or continue moving until acted upon by an external force. It helps us understand the behavior of moving vehicles, the effectiveness of seatbelts in preventing injuries during sudden stops, and even the motion of objects in space.
5. What is the significance of understanding Newton's First law of motion?
Ans. Understanding Newton's First law of motion is significant because it forms the foundation of classical mechanics. It allows us to predict and explain the behavior of objects in motion, analyze forces acting on them, and design systems that take into account the principles of inertia. This law is fundamental to many scientific and engineering disciplines and has numerous practical applications in our daily lives.
