Forces and Equilibrium Test Review

This review covers the essentials of forces and equilibrium through Free Body Diagrams (FBDs). Students will learn to draw FBDs for various objects, analyze their motion, and understand the concepts of balanced and unbalanced forces. Scenarios include a giant pineapple being pulled and a hanging mass experiencing tension. Key calculations include finding normal force, coefficient of friction, and the effect of mass on friction. This guide emphasizes the link between forces, motion, and diagrams in physics.

  1. Forces and Equilibrium Test Review

  2. Draw the FBD for the object below.

  3. Draw the FBD.

  4. Describe the motion and explain. The object speeds up because the forces are not balanced.

  5. Draw the FBD for the giant pineapple as it is being pulled at a constant rate.

  6. What is the force of friction?

  7. Find the Normal Force. Fn + Fty = Fg Fn = 1975.8 N

  8. Find the coefficient of friction. Ff = u Fn 1150 N = u (1975.8 N) u = 0.58

  9. What would happen to the force of friction if the mass were doubled. It would increase because the normal force would increase.

  10. What would happen to the coefficient of friction if the mass were increased? Nothing, the surface didn’t change.

  11. Draw the FBD for the hanging mass.

  12. What is the unknown tension force?

  13. What is the mass of the object?

  14. What is the tension force is the sofa is being pulled with a constant velocity? Ft = 448.45 N

  15. Draw the FBD with a x and y components.

  16. Find the unknown tension forces.
