Solve problems involving linear motion using the linear motion equations
Linear Motion
2.1
Linear Motion
Distance, d
Total length of path an object travels from one point to another.
Displacement,s
The shortest distance between two points.
Formulas for distance, speed & acceleration
\(v=\dfrac{d}{t}\)
, where
\(v=\text{speed},\;ms^{-1}\\ d=\text{distance},\;m\\ t=\text{time},\;s\)
\(v=\dfrac{s}{t}\)
, where
\(v=\text{velocity},\;ms^{-1}\\ d=\text{displacement},\;m\\ t=\text{time},\;s\)
\(a=\dfrac{v-u}{t}\)
, where
\(a=\text{acceleration},\;ms^{-2}\\ u=\text{initial velocity},\;ms^-1\\ v=\text{final velocity},\;ms^-1\\ t=\text{time},\;s\)
\(s=ut+\dfrac{1}{2}at^2\;\;\rightarrow\;\;\text{use this formula when there is no v given}\)
\(v=u+at\;\;\rightarrow\;\;\text{use this formula when there is no s given}\)
\(v^2=u^2+2as\;\;\rightarrow\;\;\text{use this formula when there is no t given}\)
\(s=\dfrac{1}{2}(u+v)t\;\;\rightarrow\;\;\text{use this formula when there is no a given}\)
TICKER TAPE
the distance between dots small
slow and constant speed
acceleration = 0
the distance between dots greater
high and constant speed
acceleration = 0
distance between dots increase
velocity increases
acceleration = +ve
distance between dots decrease
velocity decreases
acceleration = -ve
