Question

Wi = mall -mg sin() = mall -y sin() all Figure 1: Diagrams for the cart/track system. measure the acceleration in Logger Pro with the cach increase of mass, and compare your results to your predictions. In Part II, you will supply a time dependent (back and forth) force to the cart by hand. A data graph will be generated for your applied force vs. acceleration, and determine the physical significance of the slope of your graph. Hint: Use Eq. (2) to help you determine what the slope of the Applied Force us. Acceleration graph means.

Explanation / Answer

As the applied force is increased, the acceleration of the object increases in the direction of the applied force and vice versa. The rate of change velocity of the object is directly proportional to the force, a larger force produces large change in the velocity of the in a give time interval, i.e large acceleration of the object.

The slope of the graph represents the mass of the object.

Newton's 2nd law states, the accleration of the object is directly proportional to the net force on the object,

acceleration = net force on the object / mass of the object

or fnet = ma, so if we plot force with acceleration with get mass as the slope
