Measurement Tools
For measuring distance
what is a meterstick
The slope of the graph of Y vs. X.
Y=mX+b
What is m
The Y-Intercept of the graph of Y vs. X
Y=mX + b
What is b
F=ma where m is constant
Force is on the Y-Axis. Determine what should be on the x-axis to get a linear graph
what is a?
For Measuring Time
What is a stopwatch
The slope of the graph of X vs. Y
Y = mX + b
What is 1/m
The Y-Intercept of the graph of A vs B
A = 2xB + 3yh/2
What is 3yh/2
K=(1/2)mv2 where m is constant
K is on the Y-Axis. Determine what should be on the X-Axis to make a linear graph
What is v2
For measuring Mass
What is a balance (Scales measure weight)
The slope of the graph of A vs. B
A = mxB/2 + 3hy
What is mx/2
The Y-Intercept of the graph of A vs. B
xA = 2yzB - x/2
What is -0.5
F = mΔv/t where m and Δv is constant
F is on the Y-Axis. Determine what is on the X-axis to make a linear graph
For Measuring Force
What is a Force Probe or Spring Scale
The slope of the graph of H vs. L
bH = 3bL - 4ak
What is 3
The Y-Intercept of the graph of X vs. Y
Y = mX + b
What is -b/m
a = Ff/m - gsin(θ) where Ff and m are constant.
Sin(θ) is graphed on the X-Axis. Determine what should be graphed on the Y-Axis to create linear graph.
What is acceleration
For Measuring velocity
What is a Photogate or motion sensor
The numerical value of the slope of the graph of K vs. U
pU = 3xK - T/J
where p=4, x=6, T=2, J=5
What is 2/9
The Y-Intercept of the graph of A vs. B
