# Kinetic energy graph example watch

1. For an object has a constant force of 10N applied to it (mass = 1kg). This implies that the acceleration is constant and = 10ms^-2.
This means that the rate of increase in velocity is constant, hence a velocity displacement graph is a straight line increasing" / " .
SO If a question as draw the graph of kinetic energy against displacement:

How come these methods have different outcomes?
work done = kinetic energy so F X d = KE which gives 10 * 10 = 100
And so a graph of KE against d would be a straight line "/" form o to 100 J
But surely KE is proportional to V^2 so the graph would be a curve as velocity is increasing?
