Force and Motion-2

Force and Motion (Part 2 of 2)

TermDefinition
STATIC FRICTION Friction existing between surfaces of objects at rest There is GREATER friction between rough surface than smooth surface
AIR FRICTION Occurs due to the object moving through the air Molecules of air moved aside Larger the object the more air has to be moved aside--greater the air friction
SLIDING FRICTION RUBBING of surfaces Objects already in motion will slow down UNLESS additional force applied
ROLLING FRICTION Friction between round objects i.e, Automobile (car) wheel and the road
FIRST LAW OF MOTION Object at rests; STAYS at rest Object in motion; STAYS in motion
INERTIA When properties of matter resist changes in motion 1st Law of Motion
SECOND LAW OF MOTION Force = MASS x ACCELERATION Amount of force needed to change objects motion or rest state Depends on mass of object & acceleration required
THIRD LAW OF MOTION 1st object EXERTS force on 2nd object 2nd object EXERTS EQUAL and opposing force on 1st object
ACTION/REACTION FORCES For every action Opposite and equal reaction 3rd Law of Motion
