Newton’s Law of Motion and Its Real-Life Applications
Here Learn the three Newton’s Law of Motion which is well explained. Please read all three Laws and understand the concept of their usage in our daily life. These laws do help us in day-to-day life as well as helps us in learning many topics of Physics and Mechanics, which derives from these Newton’s Laws of Motion.
Newton’s First Law of Motion: The Law of Inertia
Newton’s first law of motion states that an object cannot start, stop, or change direction by itself. It needs some external force to cause a change in motion. This property of massive bodies to resist changes in their state of motion is called inertia. Newton’s first law is also known as the law of inertia.
Statement: A body remains at rest or moves straight line (at a constant velocity) unless acted upon by an external force.
Real-life application: Shake up that bottle of ketchup! When you shake that bottle, you bring the bottom down, then suddenly you stop. It is inertia that causes the ketchup to come out of the bottle.
Newton’s Second Law of Motion
The second law of motion discusses what happens to an object when acted upon by an outside force. The Newton Second law of motion states that the force applied to the body is the same as the product of its mass and acceleration.
Statement: Newton’s 2nd law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Newton’s Law of Motion Formula: F=ma
Real-life application – Your friend weighs less than you, but you both walk, exerting the same amount of force. Your friend will go a good deal faster than you because the acceleration used by them would undoubtedly be higher.
One of the main reasons people constantly try to reduce the mass of objects is to increase their speed and acceleration. All of the factors affect each other. If something has much more mass, then exerting more force will make it move faster.
Newton’s Third Law of Motion
In this Newton’s Third Law of Motion, we discuss the action and reaction with their use in daily life.
Statement: For every action, there is an equal and opposite reaction. If one body exerts a force on the second body, then the second body exerts an equal force on the first body.
Real-life application – Hitting the Wall with Your Fist! There are two forces, your force and the other is an equal and opposite force applied by the wall on the fist. Hence, the harder you hit the wall, the more force is exerted on your fist by the wall; this is why you get hurt more. So don’t hit the wall because you will get yourself hurt.
Newton’s Laws of Motion Questions & Answers
Question 1: A box of mass 2 kg and a force of 20 N is acting on it in the positive x-direction, and a force of 30 N in the negative x-direction, then find its acceleration?
Answer: To find acceleration, we need to calculate the net force.
Fnet = 20 N – 30 N = -10 N
Mass = 2kg
As we know, F=ma so to find acceleration, we have to divide the force by mass as per formula a=F/m
