Where would you experience each of these terms/concepts in our lives
- 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.
- 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.
- A moving bike stops when the force of brakes are applied.
- As a ball is thrown towards the sky, gravitational
force attracts the ball downwards towards the ground.
- Within a tug of war game, each team player
applies the force of pulling in order to tup the rope
into the teams direction.
- Applying force whilst wringing (squeezing) a wet cloth in
order to reduce the quantity of water soaked within the
cloth.
- Force is applied on the ground for a rebounding effect in order
to walk.
- Force is applied whilst opening as well as closing a door,
producing a push and pull effect.
- 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.
- 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.
- 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.
- 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.
- 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.
- Air Resistance
- 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.
- The same process occurs towards a plane, as the force of air
resistance slows the aircraft down, ensuring for a safe flight.
- 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.)
- 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.
- Friction – Frication plays a significant role towards many
everyday processes.
- 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.
- The force of friction is generated towards the bottom of a
trashcan whilst sliding against the concrete.
- 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.
- A person sliding down a slide is an example of sliding friction.
- 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.
- Frication process a sled to slide across snow or ice as well as skis.
- Frication is caused as a paper on the roller, slides through a fax machine.
- 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.
- Frication is caused as a card and an envelope when the
card is being slid within the envelope.
- 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.
- The friction between two books whilst sliding one
into place on a bookshelf.
- 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.
- The frame and the edge of door sliding against one another produces the motion of friction.
- Friction allows for heat to be generated by rubbing both hands
together.
- A vegetable drawer sliding against the holder with the fridge
causing the force of friction.
- A rag and the counter it is being
used to clean, causing the effect of
friction.
- 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.
- A coaster sliding against a table causes the force of frication.
- Electrostatic force
- 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.
- Non-contact force produces, electrostatic energy, for example,
a balloon ‘rubbed’ with a cloth resulting in its attraction.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Magnetic Force
- 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.
- Magnetic force is utilised within speakers, which
convert electrical energy into sound energy.
- Magnetic force is used within TV screens, computer screens,
telephones as well as tape recorders.
- The most important use of magnetic force, is the magnetic
compass which is used to find the geographical directions.
- 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.
- ATM cards obtain magnetic force, where a
magnetic strip located on the card stores
vital information.
