Newton’s Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass. This law is expressed mathematically as , where is the force applied to the object, is its mass, and is the resulting acceleration.
Newton’s second law of motion: fundamental law of dynamics
The fundamental law of dynamics, Newton’s second law or fundamental law postulates that the net force that is applied on a body is proportional to the acceleration it acquires in its trajectory.
Newton’s second law Formula
F = ma
F = net force
m = mass, expressed in Kg.
a = acceleration, expressed in m/s 2 (meter per second squared).
Examples Of Newton’s Second Law Of Motion
Here are 3 Examples Of This Law are given below:
- Pushing a Car:
- If you push a car with a certain force, it will accelerate in the direction of the force. The harder you push (greater force), the faster the car will accelerate. Similarly, a heavier car (greater mass) will accelerate more slowly for the same force.
- Kicking a Soccer Ball:
- When you kick a soccer ball, the force you apply determines how quickly the ball accelerates. A stronger kick (greater force) will result in a faster acceleration. The mass of the ball also plays a role; a heavier ball will be more difficult to accelerate.
- swinging a Pendulum:
- The motion of a pendulum is influenced by the force applied when it is set in motion. The acceleration of the pendulum bob is proportional to the force applied and inversely proportional to the mass of the bob.
Newton’s Second Law helps to understand how the motion of an object is affected by the applied force and the object’s mass. The relationship between force, mass, and acceleration is fundamental to the understanding of motion in classical mechanics.
