Next Wednesday is our next Scientific Investigation day and we will be looking at the topic of ‘forces’. In preparation for the day, please can you share your knowledge about this area. For example: describe the different types of forces that you know; can you think of any experiments you might like to do to test forces or maybe research a famous scientist within this field.

We look forward to reading your blogs and will share them on Wednesday morning in class.

    What i have learnt about forces. If you rub something against a table or anything else like a table it will cause friction. But if its a smoother surface then you don’t have that much force and friction because the thing that you’re rubing can slide about more. Any kind of force is really just a push or a pull. Magnetism is a type of force. A magnet might pull an object toward it or push it away. Springs and elastic are also types of force. Push against them and they resist. They spring back with the same force you gave them. The force definition is something that causes a change in the motion of an object. The modern definition of force (an object’s mass multiplied by its acceleration) was given by Isaac Newton in Newton’s laws of motion. The most familiar unit of force is the pound. Finlay

    A force is an object to undergo a specific change. Unbalance forces cause changes of speed,shape or direction. Graitational forces act between masses. Friction opposes motion.

    A force is a push or a pull. They can be balanced or unbalanced. If the are unbalanced they can change the shape of objects and can change the way there moving. Movements are changing forces.

    A force is measured in Newtons.
    A force can make a heavy rock to slide across easily.
    When a an object scrapes the floor it creates something called friction.

    Archimedes was a famous Greek scientist from more than 2000 years ago. He lived in Syracuse. The king asked him to work out how much gold was in his crown. But how could Archimedes work this out without breaking the crown? He found out when he had a bath that water was pushed out of the bath when he got in. Archimedes realised that he could use this to work out how much gold was in the crown. When he discovered it he shouted “Eureka!”. By Sadie

    I found out some facts about Sir Isaac Newton, one of the most influential scientists of all time! Born in England, Newton was a physicist, astronomer and mathematician. He published a book in 1687, which is regarded as one of the most important books in the history of science! Philosophae Naturalis Principia Mathematica describes universal gravitation, and the three laws of motion. His law of gravitation explains the attraction between bodies with mass (solid objects), for example the Earth and the Moon. Newton’s laws of motion explain how forces act on a solid object to affect its motion.
    Newton said that his theory of gravity was inspired by watching an apple fall from a tree. One of Newton’s famous quotes was, “I can calculate the motions of the heavenly bodies, but not the madness of people.”

    Archimedes was sitting in a bath after the king told him to see how much his crown was worth, he was sitting in the bath around 2250 years ago and he had finally worked it out so he shouted EUREKA!!!!!!!!, Max.

  7. Rosemary Caller says:

    I know about friction, gravity and inertia. I know that gravity holds the planets in their orbit and keeps us from floating of into space. Without gravity the Earth wouldn’t even have formed! Friction is the opposing force for every moment. Inertia is the force that stops things from falling out of a basket spun around really fast when it’s upside down. An object will move continuously unless a force acts upon it. If you throw a ball up it falls back down because of gravity. This proves this point. If you apply a force to an object an equal amount of force is applied to you.

    Force is measured in newton’s. A force is either a push, pull or twist. Friction is the action of one surface or object rubbing against another.

    winmarleigh yesssssss!!!!!!!!!!!!!!!!!

  10. 0722012db says:

    Forces are measured in newtons and can push pull or twist an object.I remember what forces are measured in because of Isaac NEWTON a great scientist who studied laws of motion.Next week,I want to learn about a force named static(might include some baloons)yes!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  11. 0722012db says:

    Winmarleigh Hall was EPIC,FANTASTIC all the good words I can name in my head.My best part was probably the zipwire but I thought it would go acros a motorway or all the way to Egypt:):)!!!!!!!

  12. 0722012ld says:

    Forces are measured in Newtons, they can be balanced ,unbalanced , pushes or pulls. If two forces are balanced it means the forces are the same size but are in opposite directions.An unbalanced force changes the way something moves and can change the speed of the object.Gravity keeps earth in orbit and friction is when two surfaces rub together there will be more friction on rough surfaces.

  13. Cody Firth says:

    A force is a push or a pull on an object resulting from the objects interaction with another object . Whenever there is an interaction between two objects, there is a force upon each of the objects .
    Different types of forces :
    Magnetic forces e.g. A magnet on a fridge.
    Frictional forces
    Applied forces
    Gravitational forces
    Air resistance forces and many more. By Cody

    There are a lot of different forces, for instance: friction, magnetism and Spring.
    A force is a push or pull.
    If you had a log and you put a bag of bricks on top of it, and then you put the log on top of a rock and you pushed down on the side of the log that didn’t have the bricks on, you would be creating less effort into moving the bag of bricks.
    The person that said “Eureka” whilst stepping into the bath is called Archimedes he said this because he learnt that water is displaced when stepping into the bath tub.

    Great posts everyone. Super knowledge already. Can you budding scientists help me? I was driving up Eastbourne Grove in the snow today, trying to reach the car park when I became stuck and had to reverse down the road. However, the car infront of me managed, quite effortlessly, to reach the car park. Why could their car manage it and not mine? Mr Vickers says that I cannot have a new car!

  16. 0722012ZJ says:

    You measure force in Newton’s,you can pull, push and twist forces. I am looking forward to our scientific day. I wonder what are we going to do and what we are going to learn.

    A force is measured in Newtons. When a surface rubs against another it is called friction

  18. 0722012eb1 says:

    Forces are measured in Newton’s and when something slides across the floor it creates a force called friction. But if it is a smother surface it will not have as much friction as the smooth surface will allow the object to slide about more. If two forces are balanced they will be the same size but in opposite directions. An unbalanced force changes the way something moves and can also change the speed of the object. By Ellen

    Hey guys. It’s me, Amelia. Mrs Vickers said share your knowledge about forces. So here’s mine about Diet Coke and mentos. You might be wondering why Diet Coke and mentos create such exciting geysers.

    It’s mostly due to a process called nucleation, where the carbon dioxide in the soda is attracted to the mentos (they are awfully cute). That creates so much pressure that the soda goes flying. We then built nozzles that make the opening smaller and that makes the geysers go even higher (I really wished Diet Coke flew out of it’s bottle) 🙁

    A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. Forces are measured in units called newtons. The unit is named after the famous physicist Sir Isaac Newton.

  22. 072year2012 says:

    A force is an interaction that will change the motion of an object when the force is unopposed. A force can cause an object with mass to change its velocity. Sir Isaac Newton was one of the first scientists to study force.

    Inertia is not a force.
    By Josephine

  24. 072year2012 says:

    Some forces are,
    Applied force, Gravitational force, Normal force, Frictional force, Air Resistance force, Tension force and Spring force.

  25. Jude Dewhurst says:

    I know that forces like gravity are measured in newtons! They are named after Sir Isaac Newton who was the scientist who discovered gravity. It happened when an apple crashed on his head and he wondered why it didn’t go up or side to side. This force is what stops everything floating away. Did you know that the Moon has 10% of the earths gravity? That’s why astronauts don’t float off it! Gravity is the force that makes the Moon orbit the Earth and the Earth orbit the Sun! Gravity on Earth comes from its core. If there was no Gravity water would float around in spheres… wouldn’t that be weird?

    I know that when something is flat, the air is under the flat thing, its slowing it down. This force is called gravity.
