3.What type of proportionality, if any, exists between the net force on an object and the acceleration of the object? Explain.
4.For each trial, comparethe slope of the regression line to the mass being accelerated. Find percent error – use your slope as your experimental value and the measurement from the balance as your accepted value. What quantity does the slope represent?
SUPPLEMENTARY QUESTIONS
1.When you push an object, how does the magnitude of the force affect its motion? If you push harder, is the change in motion smaller or larger? Do you think this is a direct or inverse relationship?
2.Assume that you have a bowling ball and a baseball, each suspended from a different rope.If you hit each of these balls with a full swing of a baseball bat, which ball will change its motion by the greater amount? Why?3.In the absence of friction and other forces, if you exert a force,F, on a mass, m, the mass will accelerate. If you exert the same force on a mass of 2m, would you expect the

Newton’s Second Lawresulting acceleration to be twice as large or half as large? What type of relationship existsbetween mass and acceleration, assuming a constant force?
4.What are the units of the slope of the force vs.acceleration graph as it is displayed?
