# Force - Time graph Question

 P: 30 Hi everybody, I was given a set of physics problems and some of them ask us to find work. The problem is, we are given a force-time graph as opposed to a force-distance graph. My question was whether there was a way of finding work done using a force-time graph. I don't see how it could be done and i haven't found anywhere where you can do it but I have a feeling it can be done. Does anyone know? Please reply either if it can or can't be done... Thank you
 P: 47 Not if the force and dt are the only info given...
 P: 47 Sry, ignore my last post. Yes, you can.

## Force - Time graph Question

Sorry, how can you find it out?

I tryed the area under the graph but that doesn't work

 P: 47 What kind of force-time graphs are they? I'm guessing they're impulse graphs (large force over relatively short period of time); if so, you can assume the impulse approximation. What does this tell you about the work done (or more precisely, the distance traveled due to a force)?
 P: 30 Yes, they are graphs with large forces over small amounts of time. I'm sorry but I can't see the connection between this graph and work and/or distance. If it helps, one of the questions talks about a railway engine of x mass moving from rest along a straight track. It then gives you the force-time graph.
 P: 30 It's ok now...I've figured out the answer Thanks everyone for your help
 P: 7 Hi, I have the same question as you. How did you find the work done using force - time graph?? Thanks.
