I did a lab experiment where we verify Newtons second law experimentally.
A glider moves along a frictionless air track and is attached to a hanging mass. We vary the hanging masses and calculate the force since we have the mass and acceleration.
We have some questions to answer and i need help
If table wasn't level how would it affect the slope and the slope of the graph that was plotted force vs
acceleration.

bobpursley,
If the table were tilted uphill, wouldn't then the force of gravity on the glider subtract from the applied force of the hanging weight? The slope would go down, as it accelerated slower.

physics lab help,
IS it true that if the acceleration increases then the graph would have a steeper slope but if the acceleration decreased then the slope would flatten out.
