Newton’s First Law of Motion Applications in Daily Life
In our daily life, we came across various examples which support Newton’s First Law of Motion. Some of the examples which support this law are,
- When the brakes of a vehicle are applied quickly, the passenger will be thrown forward due to the presence of inertia. Inertia tries to keep the passenger moving. This is the reason why it is recommended to wear seat belts while travelling by vehicle.
- A roller coaster uses the principle of inertia. It continues to move in the same direction at a constant speed until the tracks act as an external force that changes its direction.
- If you slide a hockey puck on ice, eventually it will stop. This is because of friction on the ice or if it hits something, like a player’s stick or a goalpost.
- A book lying on the table remains at rest as long as no net force acts on it.
- A marathon runner continues to run several meters beyond the finish line due to inertia.
- If pulled quickly, a tablecloth can be removed from underneath the dishes. The dishes remain still unless the friction from the movement of the tablecloth is not too high in magnitude.
- Men in space find it more difficult to stop moving because of a lack of gravity acting against them.
- Inertia enables ice skaters to glide on the ice in a straight-line motion.
Newton’s First Law of Motion
Newton’s First Law of Motion: Newton’s First Law of Motion states that a body always opposes its change in the state of motion. Newton’s Laws of Motion were first proposed by Sir Isaac Newton in the late 17th century. Newton’s First Law of Motion finds its importance in various other laws and it is one of the fundamental laws of physics. It also finds its importance in various real-life examples.
In this article, we will learn about Newton’s First Law of Motion, its examples, real-life applications of Newton’s First Law of Motion, Newton’s First Law of Motion equations, and some practice problems on Newton’s First Law of Motion.
