Applications of Newton's first law, second law and third law of motion. (10 for each law)
There are many more applications of Newton’s first law of motion. Several applications are listed below.
-
Blood rushes from your head to your feet while quickly stopping when riding on a descending elevator.
-
The head of a hammer can be tightened onto the wooden handle by banging the bottom of the handle against a hard surface.
-
A brick is painlessly broken over the hand of a physics teacher by slamming it with a hammer. (CAUTION: do not attempt this at home!)
-
To dislodge ketchup from the bottom of a ketchup bottle, it is often turned upside down and thrusted downward at high speeds and then abruptly halted.
-
Headrests are placed in cars to prevent whiplash injuries during rear-end collisions.
-
While riding a skateboard (or wagon or bicycle), you fly forward off the board when hitting a curb or rock or other object that abruptly halts the motion of the skateboard.
Examples of Newton's Second Law in Everyday Life This law of Newton applies to real life, being one of the laws of physics that impacts most in our daily lives:
1- Kicking a ball When we kick a ball, we exert force in a specific direction, which is the direction in which it will travel.
In addition, the stronger that ball is kicked, the stronger the force we put on it and the further away it will go.
2- Capture the ball by hand Professional athletes move their hands back once they catch the ball as it provides the ball more time to lose its speed, and in turn apply less force on its part.
3- Push a car For example, pushing a supermarket cart with twice as much force produces twice as much acceleration.
4- Pushing cars On the other hand, pushing two supermarket trolleys with the same force produces half the acceleration, because this varies inversely.
5- Push the same car full or empty It is easier to push an empty supermarket cart than a full one, since the full cart has more mass than the empty one, so more force is needed to push the cart full.
6- Pushing a car To calculate the force needed to push the car to the nearest petrol station, assuming that we move a car of one ton around 0.05 meters per second, we can estimate the force exerted on the car, which in this case will be about 100 Newtons.
7- Driving a truck or a car The mass of a truck is much larger than that of a car, which means it requires more power to accelerate to the same extent.
When, for example, a car is driven 100km on a highway for 65km, much less petrol will certainly be used than if it had to be driven at the same speed for the same distance in a truck.
8- Two people walking together The same reasoning above can be applied to any moving object. For example, two people walking together, but one of them has a lower weight than the other, although they walk with the same amount of force, who weighs less will go faster because their acceleration is certainly greater.
9- Two people pushing a table Imagine two people, one with more force than the other, pushing a table, in different directions.
The person with greater strength is pushing towards the east, and the person with less force towards the north.
If we add both forces, we get a result equal to the movement and acceleration of the table. The table, therefore, will move in a northeasterly direction, although with a greater inclination towards the east, given the force exerted by the strongest person.
10- Playing golf In a golf game, the acceleration of the ball is directly proportional to the force applied to the club and inversely proportional to its mass. In the way influences the force of the air that can cause a small change in its direction.
