## Homework Statement

we used a cart and a pulley connected, and we added hangers with different masses. masses on hangers were: 0.02, 0.03,0.04, 0.05, 0.06,0.07 (kg) and the forces measured with GLX machine were: 0.19, 0.29, 0.39, 0.49, 0.59, 0.69. then we found out our acceleration and we graphed everything. Force on y-axis and acceleration on x axis. and we got our equation from the trend line which was: y=2.16+0.11

question: what is the value (including units) and the meaning of the slope of your graph?

what is the value (including units) and the meaning of the Y intercept?

## Homework Equations

slope of our graph would mean mass since, F/A=M

## The Attempt at a Solution

slope of our graph would mean mass, according to the formula we know derived from Newton's second law of motion, but our masses weren't constant. So what would the slope of the graph mean?

and what does Y intercept of the graph mean?
