Forces
Contact forces
push
B Facts about push: it is a moment that you can control e.g. pushing a door open, pushing a door bell to ring.
-
C: A examples of push force: hockey player pushing a ball across the field. Pushing a door open, pushing a pram or trolley.
-
The factors that might influence are ... the force of the push, the type of ball and size, weight and material of ball plus the size, weight and material of the the bat.
A mechanical systems use a push force can be a pram, trolley, a can squisher in the recycling place and a keyboard.Gravity is an example of a push force that is non-contact as we are pushed down by the force of gravity on earth.
pull
-
B: The bigger the force, the more powerful it is and the faster it moves along. The opposite of push.
-
E: Pull can be coverted into push if you come from the other way. An example of a non-contact pull force is magnetism which involves a polar force. Pulley systems are a good example of a mechanical pull force.
C: Examples: Opening a door, pulling a chair out, pulling the blind down.
twist
-
B: The shape of a twisted object can be called torsion. The affect of the twist forces on objects can result in a change to the way .they can move and can change their shape
-
C: The twist force involves pushing away from you and then turning becomes a pull force. So in the process twisting has a pull force. Screwdriver or wrench is a mechanical system of a twist force. The process of the twist is called torsion.
The twist force can be changed into a push force because you can push to the left or right or to the side to begin the twist. Mechanical systems that use a twist are a screwdriver, rope, turning of a lid, dril and wench action is a twist. The twist force is actually called torsion and it is a combination of a pull and push force.
friction
Examples of Friction: water slide, just a normal slide, sliding across carpet and sliding across floorboards, rub sticks together to create fire.
Facts about Friction: Wheels are a good example of reducing friction but they need friction to work. It is really tough to stand up without friction. Fluid friction is used in water parks to help us slide down the slides.
A: Friction is a force that holds back the movement of a sliding object. friction works in the opposite direction in which the object is moving
-
-
normal
C: a book on a the table - the force is coming up vertically. A person leaning against a wall - the force is horizontal.
-
b: the force depends on the weight of the object being supported. The force is usually exerted in a vertical fashion however on occasions it can be exerted horizontally.
A: the normal force is the force placed upon an object that is in contact with another stable object
-
non- contact
gravity
-
B: that with gravity the ground will move to the moving object. Without gravity everything will float in the air.
-
C: Gravity Examples: Once you throw a ball it comes down. the force from the moon that causes the tides of the ocean.
A force that causes a rock to fall down a hill.
Observations from Questions: The further away the planet is to the sun the slower the planet moves. The bigger the sun the force is stronger. The one with the little red things move faster to it and the plain yellow one moves fast but at a consistent speed.
electrostatic
C : examples: Hair on trampoline, rubbing of a balloon with wool, lightening, and rubbing socks on carpet and touching someone.
-
D: 
A: Electrostatic is an electrical charge that is created when electrons are transferred to or removed from an object.
E: The results of Electrostatic can be seen in our everyday environment. We don't see the force but we see the result. eg. sugar, bubble in the sink.
magnetism
C Examples of Magnetism: The Earth is a magnet which helps bird find their direction when migrating, a compass is a are another example which helps in directions, refrigerator magnets which help to seal and close the doors, scrap yard and steel mill lifting system.
B: Facts about Magnets ... the earth is a magnet, There is an invisible force field with a North and South Pole. Iron fillings can show the magnetic fields create by magnets.
-
a: The magnetism force is an invisible force or field. The magnetiic force in a magnet flows from the North pole to the South pole. This creates a magnetic field around a magnet.
-
nuclear force
-
-
B: The force about 10 million times stronger then the chemical binding that holds atoms together in molecules. There are two types of nuclear forces - which act between all of the particles (neutrons, protons) where opposites attract. An electrical force is only when two protons repulse each other.
C: An excellent example of nuclear force is in nuclear weapons . A very destructive power. Another example is in radiocarbon dating.
