Physics Defintions Flashcards
Static Friction
force opposes tendency motion stationary object rel to surface
Kinetic Friction
force opposes tendency motion moving object rel to surface
Inertia
Property resist change in state of rest or const vel
Newtons 1
const vel/rest remains until fnet>0
Newtons 2
When fnet acts, obj a in direc of fnet. A direc prop fnet inverse prop mass
Newtons 3
Obj A exerts force on obj B, obj B exerts = mag opp direc on obj A
Grav
Every body attract every other body force direc prop product masses inverse prop square distance between
Coloumbs
Electrostatic f of attrac/repulse exerted by one charge on another obj direc prop product charges inverse prop square distance between
Isolated system
a system where resultant external force is zero.
Electric Field
Region in space where electrostatic charge experiences a force
Electric Field Strength/At a point
electrostatic force experienced per unit positive charge placed at that point
Ohms Law
Current along a conductor direc prop to potential difference along the conductor provided temp constant
Power
Rate at which work is done
Resistance
Ratio of potential difference across a resistor to current in the resistor
Potential Difference
Energy transferred per unit charge flowing between 2 points through a conductor
