Friction
Friction creates heat.
What does friction create?
Because the greater the force, the greater the change in motion.
What does the force have to do with the change in motion?
The energy of an object at rest at a high place.
What is potential energy?
The energy of something in motion.
What is kinetic energy?
Motion is described by speed and direction.
what is motion described by?
It is easy to stand and you won't slip.
What happens when there is a lot of friction?
The bigger an object, the less effect a given force will have on the object.
How does how big the object is affect the motion?
Height and The pull of gravity give an object potential energy.
What gives an item potential energy?
As you go down a hill kinetic energy increases.
As you go down the what increases?
Changes in motion are related to force and mass.
What are changes in motion related to?
You will slip easily and fall.
What happens when there is not a lot of friction?
It will stay in motion.
If a object is in motion then what will it do unless it is acted on by an outside force?
Potential energy is an object at rest.
Is potential energy an object at rest or an object in motion?
As you go down a hill potential energy decreases.
As you go down the hill what decreases?
That opposes motion.
Friction is a force that ______ Motion?
The resistance of motion created by two objects rubbing against each other.
What is friction?
A push or a pull.
What is a force?
A ball at the bottom of a hill would not have a lot of potential energy.
If a ball was at the bottom of a hill would it have a lot of potential energy or not a lot of potential energy?
Kinetic energy.
Moving objects have ______ energy?
Kinetic energy.
Moving objects have ________ Energy?
Then everyone would slip,slide, and fall everywhere.
If friction wasn't a thing then what would happen?
A object at rest will stay at rest unless a outside force acts upon it.
An object at rest unless an outside force is acted upon it it will?
An object at the top of a hill would have a lot of potential energy.
Would an object at the top of a hill have a lot of potential energy or not a lot of potential energy?
Opposite
Kinetic energy is the _______ of potential energy
Yes or No, Trick question. ;)
Is motion important?
