Question
Two people are pushing a car in opposite directions with forces of 100 N and 70 N. What is the resultant force acting on the car Explain your answer using Resultant forces and resultant force.
Answer
30 N to the left
Explanation
A strong answer should address calculate resultant force for forces acting in opposite directions directly. Use the context of Resultant forces within Forces and their interactions, then state the relevant forces or motion reasoning with units where needed. The answer is correct when it names the key physics quantity, keeps resultant force and balanced forces distinct, and links the conclusion back to the approved learning objective.
Common mistake
Confusing Resultant Force Calculation
Students often incorrectly add or subtract forces acting in opposite directions without considering their magnitudes properly.
To calculate the resultant force, ensure to subtract the smaller force from the larger force and indicate the direction of the resultant force.
