1. The problem I have trouble understanding slope and area on graphs. For a force as a function of time graph the area is equal to the impulse. Why is that? And what is the slope equal to? How do I know? 
1. The problem I have trouble understanding slope and area on graphs. For a force as a function of time graph the area is equal to the impulse. Why is that? And what is the slope equal to? How do I know? 2. Relevant equations p=mv fΔt=mΔv 3. The attempt at a solution So the slope should be equal to f/t? What on earth is force divided by time equal to? And is the area underneath the graph always equal to y*x (in this case y=force, x=time)? So area = f*t = impulse?
