What is the calculation for speed?
Speed = Distance/Time
Speed = Distance x Time
Speed = Time/Distance

It can do all of the above
What is Friction?
It is a force that always acts in the same direction as movement.
It is a force that sometimes acts in the same direction as movement.
It is a force that always acts in the opposite direction as movement.
It is a force that sometimes acts in the opposite direction as movement.
It is the scientific name for movement.
What is an advantage to Friction?
It allows things to start and stop
It allows you to breathe
It supports your muscles
What are two disadvantage to Friction?
It allows objects too move to fast
It always wastes energy
It slows you down
What is a pivot?
A pivot creates energy
A pivot is something that is used to convert light energy into electricity
A pivot is the point around which rotation happens.
True or False: Forces cause objects to turn around pivots.
True
False
False, Forces cause objects to change direction at a pivot.
What is a moment?
