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.
