Forces
Contacts
Push
C. Experiment 1, Example: Squashing a lump of Plasticine which is pushing the Plasticine into another shape/form.
Explanation: A push force is when one object puts an unbalanced force onto another causing it to move in the direction that the force had pushed it.
Fact: The Majority of forces use the forces push and pull but, if the forces are balanced whilst pushing the object it can make it change shape, depending on how much force is put on the object.
This picture is representing a push force in action (the man putting force onto the trolly)
Observation From Questions: 1 - If you hit a ball with a bat the things that will help the bat go further will be the amount of force that is put onto the bat with both way as, if the bat and ball is only slightly unbalanced then the ball won't travel as far. Compared to when the ball is hit using a strong push force which will differ the distance.
2 - A mechanical system that uses a push force is pushing a car to help it get back into movement.
3 - A push force can occur on a non contact force for example a gravitational force is really strong but to keep it from going through the floors a push force must be in action.
Friction
Explanation : Friction is the force between the objects that are sliding or trying to slide across each other.

This is a picture of the football hitting the ground which slows down its movement.
Pull
-
Fact: The harder you pull something the further it will travel towards you in a quicker motion as the forces being acted upon are strong.
-
This is an image of a pulling force in action - as you can see the lady is pulling her suitcase.
Observations from Questions: 1 - I believe that you can't convert a push force into a pull force as they are two opposite forces.
2 - A pull force can be a non - contact force as magnetism is a force where two object are attracted to each other, pulling them together.
3 - A mechanical system that uses a pull force is the car jacking scene when the car is pulled upwards.
Twist
-
-
Example: A twist force is something that is used to make something move in a direction, mainly in a circle direction so twisting a jar would open it and twisting it the opposite way would make it tighter or closed.
Picture: This picture is showing in action a twist force of someone twisting their wet towel to get the water off.
Observations From Questions: 1 - I believe that a push force can't be converted into a twist force as, you are pushing the force further away from you which would make if harder for the force to be twisted.
2 - A mechanical system that use a twist force would be a rotational mechanical system where a wrench is being twisted.
3 - A twist force could be known as not a proper force because when in the action of the force you could also just being pushing or pulling the force around.
Normal
Explanation: A normal force is the normal force that is the support force exerted upon an object that is in contact with another object.
-
Example: An example of a normal force is when you are walking which is applying a normal force to the ground.

Non - Contact
Gravity
C. Experiment 1, Example: When the ball hits the floor it creates gravity and then a pulling force comes in and makes the ball bounce back.
Explanation: Gravity is a force that tries to pull to attracted objects together but, the earth's gravity is what keeps us on the ground and makes things drop.

Electrostatic
C. Experiment 1,Example: Rubbing a balloon on woollen fabric then bringing to towards someone's hair causing an electrostatic force

Magnetism
C. Experiment 1, Example: Using a magnet and moving it towards a paperclip creates a magnetic force making the paper clip connect to the magnet from an inch or less away.
Explanation: Magnetism is a force where two objects are attracted to each other which causes them to be pulled together.
Fact: All magnets have two poles, the north pole and the south pole.
