PHYS 165 - Test #1
3 commonplace relationships inside the bodily international - ANS-linear, quadratic, and inverse
7 Base Quantities and its 7 SI Units - ANS-1) Mass ------------------------Kilogram (Kg)
2) Length ---------------------Meter (m)
3) Time ---------------------- -Second (s)
four) Temperature ---------------Kelvin (ok)
5) Electric Current (EC) - ----Ampere (A)
6) Amount of Substance (AS) ---- Mole (mol)
7) Luminous Intensity (LI) - --Candela (cd)
Acceleration-Time graphs - ANS-a vs t
slope of V-T graph = upward push/run = ΔV/Δt
Accuracy - ANS-Measures how near the experimental cost is to the theoretical (regularly
occurring) cost
Average Acceleration - ANS-<A> = (Δv)/(Δt)
Δv = Vf-Vi
Average Speed - ANS-<v> = (d)/(Δt)
Average Velocity - ANS-<V> = (Δx)/(Δt)
Base Quantities - - ANS-Quantity that is in reality now not essential; no longer definable in
phrases of other quantities.
(3) examples
- Length
- mass
- time
Concept of a controlled test - ANS-An test in which all quantities affecting the experiment have
consistent values, except for the independent and based variable.
Continuous Quantities - ANS-approximate numbers, measuring, rational numbers.
Ex: period, mass, time.
Sigfigs: includes finite numbers so worry in calculations.
Controlled Experiment steps - ANS-1) Devise a CE in which all portions stay constant except for
the unbiased and established variable
2) Collect statistics by means of selecting values for unbiased variable and file the impact on the
established variable
three) Construct a (Dep vs Indp) graph with GGT and draw a satisfactory match curve that
approximates information points.
4) Find an equation for the high-quality match curve, assuming there is a nice relationship and
order in the universe
