Name Ashley Mesina Net Force Particle Model Quiz 1: Modified Atwood's Machine Date Pd The experiment you just completed looks something like the apparatus pictured below, where a falling mass tows a cart by string that passes over a pulley. Friction can be ignored. FW 1. In the space to the right of the figure sketch a force diagram for the cart on the table. 2. Suppose that the hanging mass is 120g. Calculate the net force on the system. m=120kg 3. If the mass of the cart was increased but the hanging mass remained the same, how would the acceleration be affected? Explain how you know in terms of net force and system mass. 4. If masses on the cart were moved from the cart to the hanger, how would the acceleration be affected? Explain how you know in terms of net force and system mass. 5. For a system mass of 600 g and a hanging weight of 0.50 N, determine the acceleration of the system.

Directions: Write TRUE is the statement is correct but if it is false, change the underlined words with the correct answer. 1. A force is a push or pull 2. Force is a galar quantity 3. The unit of force is Newton (N) 4. In general, a body can have several forces acting on it at the same time 5. Inertial frame of reference are reference frame where Newton's First law are observable. 6. Another effect of a balanced force, equilibrium, is that a body accelerates. 7. The heavier the object, the lesser the inertia. 8. Forces acting on a body are unbalanced if the resultant force is not zero 9. In an inertial reference frame, No forces should be exerted within the frame. 10. Normal force is lateral in nature. П. Identify Action Reaction Pairs A student in hot air balloon ascends vertically at a constant speed. Consider the four forces in this situation: Fl= the weight of the baloon F2= the weight of the student F3= the force of the student pulling on the earth F4= the support force of the…

Free Body Diagrams 1. Draw a free body diagram to represent all of the forces acting on a book that is at rest on a table. 2. What are the features of a good free body diagram? What is the best way to represent the interaction itself? Why is the length of each vector important? 3. How should the length of the arrows representing each force compare for the book on the table? Why? 4. Let's place a second book on top of the book on the table. Draw a free body diagram for each book. Which forces are of equal magnitude? 5. None of the forces on the diagram of the first book should show up on the diagram of the second book and vice versa. Why is this? 6. What type of force does the top book apply on the bottom book? Why would it be inaccurate to say that the weight of the top book acts on the bottom one? 7. How does the free body diagram of the lower book compare to the free body diagram you drew in question 1? Which forces changed and which stayed the same?
