Contact forces

Pull
-
When you are pulling on a object you are using friction because the object is moving on the ground causing friction.

Non-Contact forces

Magnitisum
Is when two magnets repel away from each other that it is what magnetism is. magnetism is caused by the charge of electric charges. Each substance is made up of atoms. Each atom carries an electric charge.
-
With a magnet, what objects can you move.
-
Electrostatic

Rub a piece of woolen fabric against an inflated balloon, and bring it towards someones hair.
- If you hit the ball in the middle of the bat and in a fast motion then, the ball will travel a long way.
- A car jack uses a push force because the jack pushes up the car with its lever.
- Yes, a push force can be a non-contact force because when you have two magnets and you put the two south or north ends against each other, they will push away from each other.
- You can turn a push force into a pull force by swapping one of the south magnets to a north side and they will pull towards each other.
- A pull force can be a non-contact force. A south magnet and a north magnet facing each other will pull together.
- Car magnets use a pull force. When the car magnet is turned on to move the car, it is pulling the car onto its magnet which means it is a pull force.
- It is not possible to make a push force a twist force. To make a push force a twisting force it wouldn't be pushing properly as it wouldn't be pushing to the side.
- Door handles use a twisting force. When you twist them a certain way they open and when you twist them the other way the door does not open.
- A twist force isn't a force because it doesn't move the object. change the shape of an object, make an object stop moving, or change the speed of an object so that means it is not a force.
- So you can define the non-contact force from each other and tell the difference from them by knowing their field.
- Some of the non-contact forces include gravity and magnetic forces. We experience gravity every day because it's the force that keeps us on the ground so we don't float in the air. And we experience magnetic forces if we have like a magnet on your fridge and you take it off that is an experience of a magnetic force.
- The four fundamental forces are gravity, the weak force, electromagnetism, and the strong force. Our list of forces is longer because we don't have the fundamental forces these are only the main ones if we did the same we might only have the same amount of forces. But we have listed all the forces.
