Concept explainers
Sketch a free-body diagram for a book at rest on a level table.
(Remember: A proper free-body diagram should not have anything on it except a representation of the book and the forces exerted on the book.)
Make sure the label for each force indicates:
- the type of
force (gravitational, frictional , etc.), - the object on which the force is exerted, and
- the object exerting the force.
1. What evidence do you have for the existence of each of the forces on your diagram?
2. What observation can you make that allows you to determine the relative magnitudes of the forces acting on the book?
How did you show the relative magnitudes of the forces on your diagram?

- 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…arrow_forwardApplication I. Direction: Solve the following problem. Put your answer on a separate sheet. 1. A piece of equipment weigh 539 N and 209 N on Earth and Mars, respectively. What is the acceleration due to gravity on the surface of the Mars? 2. Two forces of magnitudes 6.0 N and 4.0 N act on a 3.2 kg body. What is the acceleration produced when these forces are acting in the same direction? What is the acceleration produced when these forces are oppositely directed?arrow_forwardPlease help me with this question; A certain force F= 20N ^i + 40N ^j is applied to an object which proceeds to move 1.0m along the negative x-axis and 3.0m along the positive y-axis. It does this because there are other forces on this object, but we will not need to think about those other forces a.) Write down ( math symbol that looks like a triangle) r in component form. b.) Determine the work done by this force F using the definition of dot product c.) Find the magnitudes of the vectors F and ( math symbol that is a triangle) r using the Pythagorean theorem. d.) calculate the angle 0 between F and ( triangle) r by utilizing your answer to part (b) and the other definition of dot product. Roughlly, sketch the two vectors to make sure that angle I reasonablearrow_forward
- Please follow the instructions carefully and provide detailed answers. Answer only if you really know how to compute it and answer all of it :( Thank you so much!arrow_forwardMake force diagrams for the following situations. Draw & label forces as arrows with appropriate length. 1. A car propelled by a 250N force with air drag of 125 N/(m/s) at winds of 1 &2 m/s (2 diagrams).arrow_forward4. A 10 kg block on a level surface is pushed by a 50 N force directed 30 degrees below the horizontal (like this: ). The coefficient of static friction between the block and the surface is 0.60 and the coefficient of kinetic friction is 0.40. a. Does the block slide or stay put? Justify your answer with a calculation. b. If it slides, calculate its acceleration. If it stays put, calculate the friction force acting on the block. Show your work.arrow_forward
- I need help ASAP thank you so much. Johnny is pulling a cart (10 kg) to the left with a force of 50 N. There is a force of friction of 40 N acting on the cart. 1. What is the net force (Fnet) acting on the cart? Include the unit and direction of the net force. 2. As a result of the net force in (b), what is going to happen to the motion of the cart? Must describe velocity and direction of the motion. Use word bank below for the answer to this. Word Bank: constant velocity, going faster/slower, to the left/right 3. What is your scientific data supporting your claim? Include unit and direction of your evidence. 4. Why does your evidence support your claim?arrow_forwardGive 5 situations that show static friction and another 5 for kinetic fiction. Just plug in the answer on the table and answer the following questions briefly, strictly don't handwrite. Please answer it completely. This is not a writing assignment and is not graded. Question Differentiate static friction from kinetic friction.arrow_forward3. Answer the following question. Put the given, formula, solution and drawing.arrow_forward
- Make it clear which question you are answering. You don't need to write an essay about it. Thank you!arrow_forwardVI. Does kinetic friction depend on the normal force? 21. Make a prediction. If normal force increases, does the kinetic friction increase, decrease, or stay the same? Give a reason r your prediction. 22. Use the Larger Area. Place the larger area of the block on the track. Record the hanging mass in the data table. Add a 500g rectangular block on top of the wood block. Change the hanging mass to 500g 23. Run the Experiment. Hang the 500g mass over the pulley. Repeat the experiment as before. 24. Change the Normal Force. Add a second 500g rectangular block on top of the block. Record the total mass in the data table. Perform the experiment again. 25. Change the Normal Force Again. Repeat the experiment by adding another 500g rectangular block on top of the block. Record the total mass. If the block does not move at all or stops after moving a short distance, add more mass to the hanging mass. Normal Force Dependence Total Block Hanging Mass Normal Force n = Mg (N) Mass Acceleration…arrow_forwardTwo masses B and C are connected with a string passing over a friction less pully, assuming the coefficient of friction between the table and block is μ=0.4 , and the acceleration of gravity g=9.81 m/s2. Solve the following questions (show all the steps of your calculations): A. Draw the free body diagram of the two masses.B. Find an expression of the acceleration of the two masses in terms of ?? and ??.C. Determine the tension in the rope in terms of ?? and ??.D. If ??= ʎ kg, ?? = (ʎ-5) kg, determine the acceleration of two blocks and the tension in the rope.(ʎ= the final two numbers of your ID +10, and, gravitational acceleration, g = 9.81 m/s2).arrow_forward
