- What are some examples of fundamental measurements?
- Mass, and temperature
- What are some examples of derived measurements?
- Speed; distance divided by time
- What is a scalar quantity?
- Quantity that has only magnitude. An example is density, volume and mass
- What is a vector quantity?
- Quantity that has a magnitude AND direction. Wxamples inlude Force, velocity and acceleration
- What is rate?
- Distance like quantity divided by time
- What is the mechanical rate formula (speed) and units?
- Speed = distance/time. The units are mi/hr ; ft/sec ; m/s ; km/s
- What is the rotary rate formula and units?
- w = q/t. The units are rad/sec
- What is the linear acceleration formula and units?
- a = Vf-Vi/t. The units are m/s2 ; ft/s2
- What is the rotary acceleration formula and units?
- µ = Wf-Wi/t. The units are rad/s2
- What is the volume flow rate formula and units?
- Qv = V/t. the units gal/min
- What is the mass flow rate formula and units?
- Qm = m/t. the units kg/hr
- What is the heat flow rate formula and units?
- Qh = h/t. the units are cal/sec ; J/h ; Btu/hr
- What is the electric flow rate formula and units?
- Qe = q/t the units are 1 Amp= 1 c/s = 6.25 x 10^18 elec/sec
- What is wieght?
- Fw = mass x gravitation constant (9.8m/s2) kg/m = N
