- a lever is a rigid bar that rotates about a point
- all levers have 3 main points:
-the place where effort is applied (e)
- the fixed point the lever rotates from called the pivot or fulcrum (p)
-the place where the thing that is moved is located.

-Some parts of a machine are designed to overcome friction. eg-wheels, balls bearings.
-Some machines use oil to lesson friction.]]> 2017-11-02 00:55:42 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/202750006 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/202751622 First Example- The chain and sprocket connect to each other when pedalling.
Second Example- When the break and wheel touch and cause the wheel to stop moving.
Third Example- Is when your butt is on the seat and if you wear silky pants you can slip easier and with normal pants it is harder to fall of due to friction.]]> 2017-11-02 01:05:41 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/202751622 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/202752980 2017-11-02 01:14:26 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/202752980 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/202753099 2017-11-02 01:15:13 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/202753099 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/202753167 2017-11-02 01:15:35 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/202753167 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/202753848 2017-11-02 01:19:29 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/202753848 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/202753884 2017-11-02 01:19:41 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/202753884 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/205103943 -When two surfaces rub on each other, the resulting friction causes the surface molecules to vibrate. this causes heat.]]> 2017-11-09 00:54:56 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/205103943 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/205104727 -Oils and lubricant on metal parts help to:

-Road tyres are smooth and thin-this reduces friction and makes the tyre move faster.

Mountain bike tyres are rougher this increases friction and that allows the bike to climb and go fast.]]> 2017-11-09 01:09:42 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/205105994 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/205106605 1. Friction
2. This stops friction and the breaks will not work.
3. Because the molecules are rubbing together.]]> 2017-11-09 01:13:48 UTC https://padlet.com/apenman1/jvvkn42x3htp/wish/205106605 apenman1 https://padlet.com/apenman1/jvvkn42x3htp/wish/207490176 Static friction is a type of force that keeps its object at rest. To start moving the object is has to be overcome with force to start moving. Once the object is moving it experiences kinetic friction.

It's how people do skiing and snowboarding.
