Without newtons second law would there be gravity on earth??????? Help!!! And also how are newtons second and third laws of motion important to your everyday life?
Newton's laws are empirical determinants of how gravity operates. Gravity operates regardless of the law.
I think I responded to the second question previously.
Since this is not my area of expertise, I searched Google under the key words ""Newton's Laws" "everyday life"" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
Great questions! Let's start with the first one:
Without Newton's second law, would there be gravity on Earth?
Newton's second law, also known as the law of acceleration, states that the force acting on an object is equal to its mass multiplied by its acceleration (F = ma). However, Newton's second law is not directly related to gravity itself. Gravity is the force that attracts objects toward each other, and it is described by Newton's law of universal gravitation.
According to Newton's law of universal gravitation, every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
So, to answer your question, even without Newton's second law, there would still be gravity on Earth because it is governed by Newton's law of universal gravitation.
Now let's move on to your second question:
How are Newton's second and third laws of motion important in everyday life?
Newton's second law of motion and third law of motion have significant implications in our everyday lives. Here's how they are relevant:
1. Second law of motion:
The second law helps us understand how objects move when forces act upon them. For example:
- When driving a car, the gas pedal applies a force that accelerates the vehicle according to the second law.
- When playing sports, the application of force determines how fast or far a ball will travel.
- In exercising, applying forces to our bodies helps build strength and muscle.
Understanding the second law allows us to predict and control the motion of objects, which is crucial in various fields, such as engineering, sports, and transportation.
2. Third law of motion:
The third law states that for every action, there is an equal and opposite reaction. It is relevant in various aspects of our daily lives, including:
- Walking: When you walk, you exert a force backward, and the ground reacts by pushing you forward.
- Swimming: When you pull the water backward with your arms, the water pushes you forward.
- Flying: The upward force generated by an airplane's wings is a reaction to the downward force of the air being pushed downward.
Understanding the third law helps us analyze forces and their effects. It is crucial in areas like engineering, aviation, and sports, helping us design efficient and functional systems.
In conclusion, Newton's second law and third law of motion are essential in understanding how objects move and interact with forces in our everyday lives. These laws provide the foundation for various fields and help us comprehend and manipulate the world around us.
