Motion graphs
displacement-time graph
displacement is area under the graph therefore l x b x h
velocity= displacement/time
acceleration-time graph
constant speed
straight line
deceleration
accelerates but the line goes down
acceleration
line goes up
speed-time graph
speed = gradient of the line=rice/run=y2-y1/x2-x1
measurements of length and time
can measure in S.I unit
length
(m) metres
time
(s) seconds
electric current
(A) ampere
temperature
(K) kelvin
mass
(g) grams
prefixes
Nano (n) (10)-9
Micro (μ) (10)-6
mili (m) (10)-3
centi (c) (10)-2
kilo (k) (10)3
methods of measuring
measuring cylinder
P
Momentum(P)=Mass(m)/velocity(v)
