Newtons Law

       HI people today's blog is about Newtons laws there are a total of three. The first Law is an object in motion will stay at motion unless and external for stops it. A object at rest will stay at rest unless an external force moves it. When a soccer ball is not in motion an external force can make it in motion like me kicking a soccer ball. When the soccer ball is in motion I can take it out of motion by putting my foot on it.


       Newtons second law says that the acceleration of an object is dependent on two thing the net force acting on the object and the mass of the object. The pic on the right the dog is accelerating at 100 N and the mass of the rock is 50 kg.









      Newtons third and finale law is for every force in nature there is an equal and opposite force. When someone is skateboarding there using force to move the board forward but friction is pulling it back.




      OK hope you liked the blog on the laws so yea BYE PEOPLE.

Gravity

      HI today's blog is about gravity. Gravity is Something that pulls something to it. Everything has gravity me, Earth, the sun even a tree has gravity it might not be strong enough to pull you to it but it has it. The sun it has gravity and its strong enough to pull planets around it. Earth for an example it pulls the moon around us.

      Galileo created a famous experiment about gravity. He went to the top of the Leaning Tower of Pisa and dropped two balls that are different sizes. The balls hit the ground at the same time so he proved that all objects hit the ground at the same time. Issac Newton also had something to do with the study of gravity. When Newton got hit on the head with the apple he figured out that it was gravity. By that apple hitting his head he figured out so much things like the three laws of gravity (for more about him I have a blog post about him)

       Mass and weight may sound the same but are different. Mass is how big an object is the weight is how heavy it is. Mass and distance has an effect on gravity the more mass it has the more gravity but distance if also important but the further you are away from something the less gravitation pull because of the distance. Gravity is one of the most important forces in the word because without it we would fly off.

       Thank you for reading the blog hope you liked it THANK YOU. BYE EVERYONE.

Force

       Hi today's blog is about force. In this blog we will talk about force, thrust, Newtons, Net Force, and centripetal force. What is force, force is a push or pull. Force is when you pull a door open or when you kick a soccer ball across a field or Pushing someone.

       
A Newton is equal to the force that would give a mass of one kilo and acceleration of one meter per second. Net Force is the overall force acting on an object. Thrust is a push or a force. An example is a fixed wing plane generates forward thrust when air is pushing in the direction opposite to flight. Thrust relates to force because they are both a push. Centripetal force is a force that makes something follow a curved path like this car its pointing forward bit the road curves. Balanced and unbalanced force is like two people pushing on a door if one is stronger and taller and the other is not its unbalanced. Balanced would be two people same strength and height.
