1. The problem statement, all variables and given/known data How does the gradient of the graph compare to the weight force? The graph is a Mass vs 1/Acceleration graph (y axis = mass, x axis = Acceleration, It was mentioned to do this.) 2. Relevant equations Explain by referring to the formula for Newton's Second Law. 3. The attempt at a solution I know that F = m * a Could someone explain what must be done and what the use of a reciprocal is? Thanks!
