Frequently Asked Questions on Applications of Newton’s First Law
What is the statement of Newton’s first law?
Newton’s first law states that an object in motion or rest remains in its state unless acted upon by an external force.
How does Newton’s first law apply to car accidents?
In car accidents, passengers have an inertia of moving forward at the vehicle’s previous speed until restrained by seat belts or airbags, demonstrating the Newton’s first law relating to the principle of inertia.
How is Newton’s first law applied to behavior of spacecrafts in space?
In space, there is a negligible air resistance or friction, so spacecraft can keep moving at a constant velocity unless propelled by thrusters, as indicated by the Newton’s law that if there is no external force, the body tends to maintain its state of motion.
How does Newton’s first law relate to skydiving?
Newton’s first law applies to skydiving as it explains why a skydiver continues moving at a constant velocity until acted upon by external forces, such as air resistance or parachute deployment.
Applications of Newton’s First Law
Newton’s first Law states that unless an external force is applied to a body, it remains in its state of motion or rest for an indefinite amount of time. This law is also known as the Law of Inertia. In other words, Newton’s 1st law discusses the necessity of an external force to bring out a change in acceleration of a body. There are a variety of instances in our daily lives where we experience the essence of Newton’s 1st Law. This article discusses various real-life applications of Newton’s 1st law.
