We all know that the great scientist has made a major contribution to the world of Physics. The laws given by Newton are totally a great foundation and many concepts lay on these laws.
Newton’s Second Law
The newtons second law is mainly based on the two terms of physics that is force and acceleration.
Newtons second law can be formally stated as
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. The acceleration of the body that is acting is directly proportional to force and is inversely proportional to the mass of the body. Hence when the force acting on a body is increased, the acceleration increases. Similarly, when the mass of the body is increased, the acceleration decreases.
Following are some examples of Newton’s Second Law of motion:
- If you use the same force to push a truck and a car, the car will have more acceleration than the truck because the car has less mass.
- It is easier to push an empty shopping cart than a full one, because the full shopping cart has more mass than the empty one. This means that more force is required to push the shopping cart.
- When a person kicks a ball the person exerts force in a specific direction, that is the direction in which it will travel. In addition to this, the stronger the ball is kicked, the stronger the force we put on it and the further away it will travel.
- Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.
- When riding a bicycle, the bicycle acts as mass and our leg muscles pushing on the pedals of the bicycle is the force.
