FORCES
THIS FORCE ALWAYS OPPOSES MOTION OR ATTEMPTED MOTION
WHAT IS FRICTION?
s = d/___
WHAT IS TIME (t)?
THESE LOADS CONVERT ELECTRICAL ENERGY INTO LIGHT, THANKS TO THOMAS EDISON'S BRIGHT IDEA
WHAT IS A LIGHTBULB?
1 g = 100 __g
WHAT IS CENTI (c)?
HE IS THE "FATHER OF PHYSICS", BEST KNOWN FOR HIS THREE LAWS OF MOTION. AND HE INVENTED CALCULUS!
WHO IS SIR ISAAC NEWTON?
THIS FORCE ALWAYS ACTS AT A 90 DEGREE ANGLE TO A SURFACE; IT'S JUST IRREGULAR THAT WAY
WHAT IS NORMAL FORCE?
WHAT IS GRAVITATIONAL ACCELERATION (g)?
THE MOST SIMPLE CIRCUIT COMPONENT, ITS JOB IS TO CREATE A PATH FOR ELECTRONS
WHAT IS A WIRE?
200 __L = 0.2 L
WHAT ARE MASS AND VELOCITY?
THIS IS THE ONLY FORCE WHOSE STRENGTH DEPENDS ON THE MASS OF THE OBJECTS EXERTING THE FORCE
WHAT IS GRAVITATIONAL FORCE?
V = I__
WHAT IS RESISTANCE (R)?
THIS CIRCUIT COMPONENT PROVIDES ELECTRICAL ENERGY; SOME DEVICES REQUIRE A FLEET OF THEM
WHAT IS A BATTERY?
0.1 kg = 1 __g
WHAT IS HECTO (h)?
WHAT IS DYNAMIC EQUILIBRIUM?
PULLING ON A ROPE, CHAIN, OR CORD RESULTS IN THIS FORCE
WHAT IS TENSION?
ME = GPE + ____
WHAT IS KINETIC ENERGY (KE)?
WHAT IS A SOLENOID?
0.2 dL = 20,000 __L
WHAT IS MICRO (μ)?
THESE SUBATOMIC PARTICLES ACT LIKE TINY MAGNETS (DUE TO QUANTUM MECHANICS); CREATE A PERMANENT MAGNET BY ALIGNING THEM
WHAT ARE ELECTRONS?
AN OBJECT FALLING AT TERMINAL VELOCITY HAS ITS WEIGHT FORCE BALANCED WITH THIS UPWARD FORCE
WHAT IS AIR RESISTANCE?
___ = Q/t
WHAT IS CURRENT (I)?
NEED A QUICK BURST OF CURRENT? HOOK UP ONE OF THESE CHARGE-STORING COMPONENTS MADE FROM TWO PARALLEL METAL PLATES
WHAT IS A CAPACITOR?
40 __m = 40,000,000 km
WHAT IS GIGA (G)?
ANY THROWN OR LAUNCHED OBJECT IN PROJECTILE MOTION FOLLOWS THIS KIND OF CURVED PATH, JUST LIKE THE GRAPH OF y = x2
WHAT IS A PARABOLA?
