Mo8-L1b: How Does Gravity Affect Forces?
Key Concept
How Does Friction Affect Forces?
How does friction affect the motion of two objects
sliding past each other?
Reducing Friction SUMMARY
How Does Friction Affect Forces?
Lubricants decrease friction and with less friction, it
is easier for surfaces to slide past each other. Friction can reduce the speed of objects sliding
past each other.
Air resistance is a type of f uid friction that
slows the speed of a falling object.
