Where would you experience each of these terms/concepts in our lives
  1. Force- The use of force in everyday life is extremely common, as it is used in order to walk, to lift objects, to throw a ball or to move a given body by a particular speed as well as direction.
    1. As a football is kicked, it moves/processes through the air at a fast pace,, however after a period of time its force decreases due to friction once the foot ball has touched the ground.
      1. A moving bike stops when the force of brakes are applied.
        1. As a ball is thrown towards the sky, gravitational force attracts the ball downwards towards the ground.
          1. Within a tug of war game, each team player applies the force of pulling in order to tup the rope into the teams direction.
            1. Applying force whilst wringing (squeezing) a wet cloth in order to reduce the quantity of water soaked within the cloth.
              1. Force is applied on the ground for a rebounding effect in order to walk.
                1. Force is applied whilst opening as well as closing a door, producing a push and pull effect.
                2. Gravity - Without the force of gravity, life on Earth would not exist, in fact planets, suns, moons, etc would not withstand within the universe (in other worlds nothing would exist). Additionally, if the quantity of gravity on Earth was much less, there would be no water as well as atmosphere withstanding in our planet.
                  1. Gravity supplies us with materials in order to build homes as well as buildings on, a location for children to run around as well as fall down onto something.
                    1. The force of gravity allows for us humans to obtain a planet in which we can stand on, a source of light as well as an atmosphere to breathe in.
                      1. With the source of gravitational force the sun will maintain the process for the Earth to orbit around the Sun. Additionally, it is essential for life on Earth, especially light and warmth form the sun in order to survive, allowing for the Earth to maintain its position, lying in a safe distance from the Sun.
                        1. With the force of gravity, the existence of the moon not only moves the oceans, however also moves the ground beneath our feet. As the moon orbits, it withdraws/ obtains a pulling force, as the Earths crust slowly up and down, generating the Earth tides, also contributing towards its motion.
                        2. Air Resistance
                          1. The force of air resistance towards a motor vehicle (car, bus, train, etc.) will encounter a significant drag motion, as it speeds through the air, acting to counter the motive force forwards, increasing air resistance as well as lowering the fuel efficiency of the vehicle.
                            1. The same process occurs towards a plane, as the force of air resistance slows the aircraft down, ensuring for a safe flight.
                              1. Additionally, the force of air resistance lowers the fuel efficiency of a commercial aircraft. (In other words if you were to travel by air, the cost based on airfare tickets would cost more compared to if air resistance were not a factor.)
                              2. Whist parachuting out of an airplane, the force of air resistance would assist in order to pushes upwards on the parachute, causing the parachute to slowly float towards the direction of the ground. As a result, if the assistance of the force of air resistance, the parachute would become worthless, developing into a dangerous landing.
                              3. Friction – Frication plays a significant role towards many everyday processes.
                                1. The use of friction is applied as two objects rub together, generating some of the energy of motion to be converted into heat (for example, the force of friction is the main source of two sticks rubbing together, eventually resulting for a fire to be produced.
                                  1. The force of friction is generated towards the bottom of a trashcan whilst sliding against the concrete.
                                  2. Whist walking, the force of friction between shoes on the ground is produced as you step forward the pushing motion of your foot backwards. Friction grasps your shoe towards the ground, allowing for you to walk.
                                    1. A person sliding down a slide is an example of sliding friction.
                                    2. The force of friction, allows for you to produce the motion of writing with the use of a pencil, it would be impossible to clasp a pencil within your hand without the use of friction, resulting for it to slip between your fingers whilst writing, as well as the graphite pencil led would not produce a mark on the paper without the force of friction.
                                      1. Frication process a sled to slide across snow or ice as well as skis.
                                        1. Frication is caused as a paper on the roller, slides through a fax machine.
                                          1. The tube on a lotion bottle and the opening to the lotion when it is pushed down to let out lotion generates the motion of friction.
                                            1. Frication is caused as a card and an envelope when the card is being slid within the envelope.
                                        2. In order for a pencil eraser to be utilised, the force of friction is essential in order to remove mistakes written in pencil. Rubbing the eraser on the lead wears out the eraser due to friction, while the particles worn off gather up the pencil lead from the paper.
                                          1. The friction between two books whilst sliding one into place on a bookshelf.
                                          2. The force of friction allows a car to start moving, producing friction against of tires against the street. Without the source of friction, the tires would just spin. Like wise, it would be impossible to stop the vehicle/bike without the friction of brakes or ties.
                                            1. The frame and the edge of door sliding against one another produces the motion of friction.
                                            2. Friction allows for heat to be generated by rubbing both hands together.
                                              1. A vegetable drawer sliding against the holder with the fridge causing the force of friction.
                                                1. A rag and the counter it is being used to clean, causing the effect of friction.
                                                  1. Jeans on your legs when putting them on, generating the effect of friction as two objects come into contact with one another as they rub/side together.
                                                2. A coaster sliding against a table causes the force of frication.
                                                3. Electrostatic force
                                                  1. Electrostatic force is produced resulting of static electricity, eg. whilst getting out of the car on a warm, day, or by touching a metal door handle.
                                                    1. Non-contact force produces, electrostatic energy, for example, a balloon ‘rubbed’ with a cloth resulting in its attraction.
                                                      1. Electrostatic force is attracted as well as repelled by static energy with extremely light objects, e.g. picking up small pieces of paper or attracting hair with a rubbed plastic comb or ruler.
                                                        1. Plastic bags result from electrostatic force, as you unwrap your lunch, the plastic bag gets charged with a positive charge, and is attracted to the negatively charged clothing, due to the fact that when one object is negatively charged where the other is positively charged, they will be attracted towards each other.
                                                          1. Photocopiers result from electrostatic force. Inside the photocopier there is a special drum, charged with static electricity and the black ink commonly known as toner. This drum attracts the toner particles but the light allows the toner only touch the marked parts of the paper.
                                                          2. Electrostatic force is produced towards events in which involve the receiving of an electric shock, e.g. playing on a trampoline mat, where static electricity if generated.
                                                            1. Lightning is another example of electrostatic forces within everyday life. When clouds rub against each other, the particles gain a charge, in which want to equalise. As the ground obtains a neutral force it is the ideal place for the particles to equalise their charge.
                                                              1. Woollen clothing obtains the force of electrostatic energy. When taking off woollen clothing the rub against the other items of clothing making the wool negatively charged. As the wool equalises its charge zapping noise occurs.
                                                              2. Magnetic Force
                                                                1. Magnetic force is produced by refrigerator magnets, as the small paper holders which are attached on the refrigerators obtains magnets at their backs in which assists them to be attached towards the surface of the refrigerator.
                                                                  1. Magnetic force is utilised within speakers, which convert electrical energy into sound energy.
                                                                    1. Magnetic force is used within TV screens, computer screens, telephones as well as tape recorders.
                                                                      1. The most important use of magnetic force, is the magnetic compass which is used to find the geographical directions.
                                                                    2. The magnetic crane utilised to lift heavy trunks produce magnetic force, as the electronics magnets (magnet which emit magnetic force only at the time when electricity is passed through them) used within are tuned on, the magnetic field increases allowing the trunks to be attached towards the magnet of the crane.
                                                                      1. ATM cards obtain magnetic force, where a magnetic strip located on the card stores vital information.
