Drawing Force Diagrams
Draw and interpret force diagrams showing forces as labelled arrows — where the arrow's length represents the force's magnitude and its direction shows which way the force acts; show multiple forces on one object; identify from the diagram…

Question 1 of 3
A 2‑kg block slides on a horizontal surface. Two horizontal forces act on it: a push of 15 N to the right and a kinetic‑friction force of 5 N to the left. Which of the following correctly describes the resultant force arrow that should be added to the force diagram?
Question 2 of 3
A student measures the length of one rod as 12.3 cm and another rod as 4.56 cm. She adds the two lengths to find the total length. What is the total length reported with the correct number of decimal places?
Question 3 of 3
A 2‑kg block rests on a frictionless horizontal surface. Two horizontal forces act on the block: a 5 N force to the right and a 3 N force to the left. A student has drawn a force diagram showing these two forces. Which arrow should be added to represent the resultant force?
