Friction is a force which when the first object/rubber moves on another object/table then it will go slower. for example if you rub a rubber on a table then it will slow down.

non-contact forces

Temporary magnet
a electrostatic force is when two objects rub on together for example if you rub a piece of metal on another piece of metal then they will both be magnetic. there are three types of electrostatic forces Temporary, permanent and magnetic.

Push 1. You hit a ball with a bat. What factors will influence how far the ball will go? The ball will accelerate down if you hit the ball down because the force will push the ball down more and more. Kinda like if you were falling down to earth the atmosphere will make you accelerate more and more.
- What mechanical systems use a push force? Chains and gears.
- Can a push force ever be a non-contact force? If so, when? Yes for example if you let go of a door then it will be pushed.
Pull 1. Can you convert a push force into a pull force? Yes for example you could push a door or pull a door.
- Can a pull force ever be a non-contact force? If so, when? No
- What mechanical systems use a pull force? A car pulling a cart.
Twist 1. Can you convert a push force into a twist force? Yes for example if you push a block of plastic with two hands then it will still brake and when you twist the plastic it will still break
- What mechanical systems use a twist force? A mechanical Anker or a mechanical well.
- Extension: A twist force is not technically a force? Why is that the case?

- What mechanical systems use a twist force? A mechanical Anker or a mechanical well.
Extension: A twist force is not technically a force? Why is that the case because its pretty much rotating.
- Can you convert a push force into a pull force? Yes for example you could push a door or pull a door.

Non-Contact 1. Extension: non-contact forces are often described as having a ‘field’ associated with them. What is a field and why is it helpful in understanding non-contact forces?
- Extension: There are more non-contact forces than what is listed in this table. What are they? Do we experience them in everyday life?
- Extension: In physics, it is said that there are four fundamental forces. What are they? Why is our list of forces larger?
-
a normal force is a contact force which the second object/table uses a support force which is exerted on another object. for example if you put a book on a table then the book will use downward force and the table will use upward force.
