Newton's Law

      Hey everyone, I'm back this week with a new post for you all and this one will be a short one. Before we begin, I have a question for you: do you think that there is a way for The Three Laws of Motion to be broken, and if so how? Leave a comment in the comment section. Ok, if you have not figured it out let, I'm going to be talking about Newton's Laws of Motion. In this post, I will be reviewing all three laws of motion and I'll make sure to give you examples.

      The first law of motion states that an object at rest tends to stays at rest. The object will remain at rest until an unbalanced force acts upon that object. If the object is in motion, it will continue to stay in motion in a straight line. An example for this law is when a person kicks a soccer ball. The ball is on the ground and is not in motion, but when someone kicks the ball, the ball is in motion and will continue to be in  motion until another force(s) acts upon the ball, in this case air resistance and gravity.

      Now that we've covered Newton's First law, lets talk about the second law. Newton's second law of motion states that the acceleration of an object is dependent upon two variables, the acceleration of the object and the mass of the object or F=MA. F stands for force, M stands for mass, and A stands for acceleration. This formula will allow you to calculate how much force it would take to move an object by multiplying the mass of an object by the acceleration of the object.

 

F=MA

      Finally, Newton's third law of motion states that for every action there is an equal and opposite reaction. The statement means that in every interaction, a pair of forces is acting on the two interacting objects. This law is why birds can fly and how we got people to the moon. Another example is fish swimming in water. A fish uses its fins to push water backwards. But a push on the water will only serve to accelerate the water. Since forces result from mutual interactions, the water must also be pushing the fish forwards, propelling the fish through the water.

Gravity

      Hey everybody, I'm back again for a new post this week. Quick question though, did you like the movie Gravity? Please answer this question in the comment section down below. Ok, this week we are going to be talking about a special type of force that I hope we are all aware of. It is the force that keeps us on the ground, and keeps the planets orbiting the sun, and in no uncertain terms lets us drop the beat. The week, I will be talking about gravity.

     

Gravity

 

      Gravity is the force that is a push or pull upon an object. This is what keeps the planets in orbit around the sun because the sun's gravitational pull is holding the planets in its orbit. Another example that's more down to Earth is if you had a box blocking your way, what would you do? Well, you would hopefully push the box out of the way. Gravity is also the most influential force in the universe. Without gravity, you and all other forms of matter would float pointlessly around in space.

      Now that we know what gravity is, let's talk about the two men that showed us what gravity is and it contribution to science. The first person to discover gravity is a man named Galileo. If his name is familiar to you than that's a good thing because he is the man who created the experiment where you drop two objects at equal level so that they would both fall to the ground at the same time. Surprisingly, the day that Galileo died, Sir Isaac Newton was born! Isaac Newton is the man that discovered that gravity's strength on an object depends on its mass and distance.

      Ok, now that we know what gravity is and how it is important, let's now talk about mass, weight, distance, and see how they all play a role in how gravity affects you. Mass is how much space an object takes up. Distance is how far an object is from a starting point. Weight is how much force is to be acted upon the object, and this is why your weight changes on different planets.

Use The Force

      Hello everybody, I'm back again with a new post for this week and I hope that I can get back into that post per week routine, but no promises. Well, this week we will be talking about something that all you Star Wars fans will be quite familiar with. We will use the force of our minds and explore what force is and how it affects the world around us. Now that we know our topic for this post, let's begin.

Force

      Force is a push or pull that is acted upon an object. Force is all around and you may not know it's there. One form of force that we are all hopefully aware of is the force of gravity which keeps us on the ground. Another type of force is action at a distance force. This type of force is what keeps the earth in a constant orbit around the sun. Another type of force is contact force. An example of this is when two cars collide into each other and one car is bumped back. These are some of the examples of force that you can see every day. Force also has a special type of measurement as well. When you measure force you measure it in Newtons. The reason why it is named Newtons is because Sir Issac Newton was the first person to discover force and how force works on objects. He also created the three laws of motion. Finally there is thrust. Thrust is the reaction force that is applied on a surface in a direction perpendicular or normal to the surface.

It's a push or a pull

      Now that we know what Force is and how it is measured, let's talk about balanced and unbalanced force and how you can tell them apart. Balanced force is when an object is at rest or in a constant speed and direction. These characteristics are of balanced force, but who wants to stay at a constant speed or stay in the same direction? Let's say that you have the need for speed, so what do you need to go faster? It's unbalanced force. Unbalanced force is when the force (push or pull) on the object is greater than the other forces acting upon it. Depending on where this greater force is applied, you would travel in that direction, may it be up, down, left, right, forwards, or backwards.

Balanced force

      Now that we know what balanced and unbalanced forces are, let's now learn about centripetal force. Centripetal force is when an object is in a circler motion moving at a constant speed. An example of this is when a motorcycle is spinning in a metal cage. The reason why the motorcyclist is able to do the spins in the cage is because of centripetal force.
