Gears
in a gears system, if power where to remain constant, what happens when you increase the torque?
speed decreases.

gravitational force
electromagnetic force

how do you convert from a vt graph to a dt graph?
find area

what type of gear experiences a force to move sideways unless is paired with another gear of the same type but facing in the opposite direction?
helical gear
what is the difference between the weight and mass?
mass is like density, it is constant. weight dep. on gravity
what is the difference between a vectoral unit like velocity and acceleration, and a scalar unit like temperature, mass, and pressure?
vectoral has direction and magnitude
what type of wave is sound?
torsional, compressional, or transverse
compressional

what two things make up torque when talking about gears? (equation talked in class)
force times moment arm
what is the mass of a table that has a gravitational force of 800 newtons on earth?
81.54 kg
what is the final velocity of an object that accelerates at 2m/s^2 from rest for 5 seconds?
10m/s
what is the orientation (inversed or the same) of the reflected wave on a fixed end scenario?
ex) a string connected to a wall
flipped
which band played eye of the tiger?
Michel Jackson
survivor
acdc
Bruce lee

which combination of gears will transfer more torque to the output and give a reason why: small gear spinning big gear or big gear spinning small gears.
small spinning big gear since the big gear spins slower so the torque is greater
how does a beam scale measure mass?
it compares the mass of an object to a known mass, by finding a balance between the two masses.
how do you add vectors using the drawing method.
add the head to the tail and draw the resultant
what happens to a wave when it travels from a heavy to a fast medium in terms of speed and wavelength?
ex) ground wave from solid rock to dirt
it is faster with a longer wavelength
which is not a rock band?
malidian
shy
great white
