Terms in this set (46)
Joules
When using the equation Ephoton= hf = hc/wavelength, Ephoton must be in
1 Kg
is equal to 2.2 pounds
A nickel
weighs about 5 grams
Displacement
the change in position of an object
Resultant Vector
the vector sum of two or more vectors (a^2 + b^2 = c^2
Inertia
equal to the mass of an object
Power
measured in watts
Energy
measured in Joules
Energy in a Circuit
is equal to power (ohm's law) x time
Strong Force
holds together particles of the nucleus
Weight (Force of Gravity)
decreases as you move away from the earth by distance squared
Constant Velocity or Zero Velocity
means the net force is zero and the acceleration is zero
Vectors
Velocity displacement, momentum and force are
Scalar Quantities
Speed, distance, time, and energy are
Acceleration
is the slope of a velocity-time graph
Velocity
is the slope of a distance-time graph
Momentum
is conserved in all collision systems
Magnitude
how large a vector quantity is
Mechanical Energy
is the sum of the potential and kinetic energy
An eV
is an energy unit equal to 1.6 x 10^-19 Joules
Gravitational Potential Energy
increases as height increases
Kinetic energy
changes only if velocity changes
Coulomb
is a charge
Amp
is current (coulomb/sec)
Volt
is potential difference (joule/coulomb)
Best conductor
short, fat, cold wires
Electron and Protons
have equal amounts of charge (1.6 x 10^-19)
Adding a resistor in parallel
decreases the total resistance of a circuit
Adding a resistor in series
increases the total resistance of a circuit
All resistors in series
have equal current (I)
All resistors in parallel
have equal voltage (V)
If two charged spheres touch
add the charges and divide by 2 to find the final charge on each sphere
Electric Fields
point in the direction of the force on a positive test charge
Electric fields between parallel plates
are uniform in strength except at the edges
Direction of a magnetic field
is defined by the direction a compass needle points
Sound waves
are longitudinal and mechanical
All angles
are measured to the normal
Light waves
are transverse
At the critical angle
a wave will be refracted 90 degrees
Doppler Effect
a wave source moving toward you will generate waves with a shorter wavelength and higher frequency
Transverse waves particles
vibrate back and forth perpendicular to the wave direction
Photon
is a particle of light
Electromagnetic waves
originate from accelerating charged particles
Ground State
is the lowest energy state of an atom
Internal Energy
is the sum of the temperature (KE) and phase (PE) conditions
Nuclear Forces
are strong and short ranged
