A car starts from rest and moves on a surface with uniform acceleration. Draw the graph of kinetic energy versus displacement. What information you can get from that graph ?

Explanation

K.E = `(1)/(2)mv^(2)" "…(1)`
Here, `u=0`
`v^(2)=u^(2)+2as" "…(2)`
`therefore` (2) in (1) K.E. = `(1)/(2)m(2as)`
`K.E. = mas`
`therefore K.E prop s`
The above equation is similar to `y=mx+c`
`therefore` Graph is a straight line

Slope of the graph is constant
`therefore` Force acting on the car.
