introduction
In this article, I will examine Newton's second law of movement with examples. Newton's Second Movement Law is the vehicle behind the movement of the body that surrounds us. The law is one of the basic principles of physics. Vino de England andHe lived between 1642 since 1727 of the ads.
What is Newton's second act of movement?
Newton's second movement states that the net force that acts on a body is the product of mass and acceleration. In other words, the second law of the Newton movement can be defined that the change in change that is directly proportional to the forcethat affects it, and happens towards force.
So that we can define this law
To apply ∝ Change in impulse / dedicated time
And the impulse is the product of mass and speed. We can write this statement in a mathematical way as
Impulse = mass x speed
Therefore, change in impulse = (mass speed of mass x) - (initial mass speed x)
Therefore, the change in impulse = mv - mu
Now we can define Newton's second law as
F = (MV - MU)/t [onde = Tempo Gasto]
Acceleration = (final speed - initial speed)/time required
What is a = (v - u)/t
Then f = m (v - u)/t, which can be rewritten as f = ma
Therefore, we wrote Newton's second movement law in a mathematical wayF =
and f = force,
M = body mass and
A = body acceleration
The violence unit is found in Newton, Mass in kilograms and acceleration in meters per second.
We apply Newton's second movement law to understand the movement of objects in several physical phenomena. This phenomenon varies from moving a rocket in the space for a car that leads to the street.
Newton's second act of movement in everyday life
Here are some examples of Newton's second movement law, which applies to us in our daily activities:
Car on a road
If a car accelerates on a road, two physical variables in the form of strength and mass would play an important role in the car. The car engine is forced to move on the street. The car is responsible for the power of the car.
In addition, the car's mass determines that it is an acceleration. This is because the car's mass is very large, the weight of the car can reduce acceleration due to gravity.
Therefore, the car accelerates at a lower speed if we compare it with an acceleration of the car with a lighter mass.
Paratrooper
If a stop jump falls to the floor, the body accelerates.
In addition, the force that acts on the paratrooper attracts it to the ground. We can easily identify this type of strength as gravity. The power of gravity and mass of his body play an important role in bringing it to the ground.
A hockey
Another example of Newton's second movement law is when an ice hockey album. If the album slips into ice, there is always a friction power that reduces its acceleration. Your acceleration.
The friction force between hockeyuck and ice will resist and limit the acceleration of the movement's law.
rocket
If we start a rocket in space, it accelerates for a specific objective. The rocket moves further up, the engine continues to function. During this process, the fuel is burned in the engine and the rocket is easier.
Thanks to a decrease in mass (burned fuel), the soft operation above the rocket will only be possible. If the rocket fuel continuesand was influenced by engine work.
When the burst increases, the rocket accelerates to space.
Shopping venture
When visiting a supermarket, you must push a shopping cart due to the items you bought. The shopping cart makes it easier.
In addition, the mass of the shopping cart and the internal article play a role in determining car acceleration.
Then you push a shopping cart for your car. APPLAS THE SECOND ACT OF MOVEMENT OF NEWTON.
A baseball ball that was hit by a bat
In this case, the power of the stick hits the ball and allows it to accelerate. The mass of the ball is a very important factor to decide its acceleration. You are greater power, the higher the acceleration of the ball.
A plane
We have an airplane as another example of Newton's second movement. If a plane moves away, its engine forces the aircraft to accelerate on the track. This acceleration helps at the level to reach its weight through float.
A boat that stands out for water
The rudder of a boat that places water helps drive the boat to the water. Things influence the rudder of the boat power, while the mass of the boat and its passengers determine the acceleration of the boat in the water.
More people and more people can influence the power of the boat and let them run faster. They with the right people who control the boat have the opportunity to win the ship game.
Soccer
When a soccer player hits a ball, turns the strength of the ball, that accelerates it, and the ball is easier to add to the air.This helps the ball accelerate as soon as the power of the leg is applied.
A basketball
A basketball player uses biceps violence to throw a ball into the net. While throwing the ball, its acceleration is proportional to the force it has applied and the basketball mass.
