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.

Ten real life examples of newton's second law of motion are :--

The second law of motion states that acceleration produced when an unbalanced force acts on an object and the acceleration produced in a body is directly proportional to force acting and inversely proportional to the mass of the body.   so F=ma F is force, m is the mass of body and a is the acceleration produced in the body.

Examples are:--

1)It is easier to push empty cart than full as full has more mass than empty so more force required to push full cart.

2)To push a car is easier than a truck as it has less mass so force required is less.

3)A cricket player moves his hands backward on catching a fast moving ball to prevent injury as force exerted by fast moving ball is high so to reduce force time is increased.

4)Use of seat belts to prevent injuries in case of fast moving car as car has large momentum which is reduced to zero at very short time hence provided with seat belts.

5)During athletics meet, a high jumping athlete is provided by cushion or sand to prevent injuries as sand helps to reduce momentum of athlete hence force is reduced.

6)Kicking a ball by player, more force applied more is acceleration in body more is the distance covered by the ball.

7)Game of tug of war the two teams pull rope in opposite direction and the team which applies larger force wins as net force in the direction of team which wins the game.

8)Karate player breaks slab of bricks in single blow as when hands move they carry velocity and when they touch slab the velocity is 0 in very short time hence force exerted is very high hence slab breaks in single blow.

9)Force of gravity that is force by which earth attract a body is more in case of heavy bodies as compared to lighter ones as f is proportional to mass of body.

10)In a golf game the player hits the ball with large force so that acceleration in body is more as acceleration increases so does the distance of the ball hence to make it travel far the player has to hit ball with greater force.
